1000mW 447nm Waterproof Adjust Focus Blue Laser Pen, retail $225.20

(www.dinodirect.com...)
Manufactured by: OXLasers China

(www.oxlasers.com)
Last updated 05-31-12






The 1000mW 447nm Waterproof Adjust Focus Blue Laser Pen (hereinafter,

probably just called a "blue portable laser" or even just a "blue

laser") is a royal blue-emitting, directly-injected diode laser. That

is, it produces deep blue laser radiation directly, without the need

for messy, fragile nonlinear crystals like those green laser pointers

and the amberish-yellow and slightly greenish-blue ones as well. It

uses a 18650 rechargeable Li:ION (lithium ion) cell -- you just charge

it back up when it poops out...never have to run to the store for

batteries.

It is advertised to output 1W (1,000mW) of laser radiation at 447nm.

This is the reason I call it a "portable laser" on my website instead

of a "pointer". Lasers designated as "pointers" must -- by US law

anyway -- have a power output that does not exceed 5mW.

***EXTREME DANGER!!!***
This laser can produce up to 1 watt of laser radiation at 447nm (royal

blue), and can cause instant and permanent eye damage from an

accidental reflection or accidental direct exposure!!! You need to know

what you're doing and have the appropriate safety precautions for a

CDRH Class IV laser device in place before you energize this laser!!!

You must also have the appropriate laser safety eyewear and *USE IT*

every time you fire up this studly little laser...you don't want to end

up like this guy:

--->

This may look funny, but I assure you folks, this is no joke!!!


It comes in a handsome aluminum body with a rather nice looking blue

finish.


SIZE



To get the laser to turn on, first be certain that the furnished 18650

cell is installed. If it isn't, then install it (see directly below),

and THEN you can activate it.

Aim the laser well-away from your face first.

Press & release the

tailcap button to turn the laser on; do the same thing to deactivate

it.

The focus is easily adjustable from just a few millimeters from the

exit aperture to infinity by simply rotating the bezel (head). Unlike

some other focusable lasers, doing this does not leave the head feeling

"wobbly" or loose.



To change/charge the battery in your blue laser, unscrew and remove the

tailcap, and set it aside.

Tip the used cell out of the barrel and into your hand, and recharge

it.

Insert a newly-charged 18650 rechargable Li:ION cell into the barrel,

flat-end (-) negative first. This is the opposite of how batteries are

installed in most flashlights, so please pay attention to polarity

here.

Screw the tailcap back on, and be done with it.



To charge the 18650 cell, place it in the charger, orienting it so its

button-end (+) positive is on the bottom of the charger.

Plug the charger into any standard (in north America anyway) two- or

three-slot 110 volts to 130 volts AC 60Hz receptacle.

A red light on the charger should now come on; this indicates charging

is in progress. When the 18650 cell has reached full charge, the light

on the charger will turn from red to green.

At this point, unplug the charger, remove the charged cell from the

charging cradle, and install it in the laser as directed above.

Current usage measures 1,632mA (1.6320 amperes) on my DMM's 4A scale.

***EXTREMELY IMPORTANT!!!***
This laser has a very large amount of {vulgar slang term for male

nads
} to it (measured at 891mW!!!), so you

***DEFINITELY*** do not want to shine it into your eyes,

other people's eyes, pets' eyes, for that matter, the eyes of any

person or animal you encounter.

Eye damage can occur

faster than the blink reflex can protect them, regardless of what

species' eyes you irradiate with this laser. So just don't do it.


And para los motivos de Cristo (and for heaven sakes and for Pete sakes

and for your sakes too) do not shine this laser at any vehicle, whether

ground-based like a motorcycle, car, or truck, or air-based like a

helicopter, airplane, or jet. And if you shoot it at a person in the

dark and he turns out to be a police officer, he may think he's being

targeted, unholster (whip out) his gun, and hose you down with it.

Waterproofness is as advertised: The tailcap, bezel, and barrel all

held a good partial vacuum when they were suctioned (the tailcap held

the vacuum even while the switch was actuated a number of times); there

are O-rings present at both ends of the barrel as well. After being

submerged in the lavatory (bathroom sink) under ~10" (~25.40cm) of

water at 81°F (27.22°C) for a couple of minutes (to simulate somebody

taking it on a brief underwater junket), nothing untoward happened to

it, and no water was found inside when the ends were unscrewed &

removed.


I submit this as proof that I really did dredge it.


The biggest downside to this laser is the fact that while this is

clearly a CDRH Class IV laser (making it extremely dangerous!!!), there

are no safety features at all that are normally required in Class IV

lasers; e.g., there is no "emissions" indicator, no startup delay, no

interlock of ANY type, and no mechanical beam shutter. This laser

behaves like a Class IIIa laser pointer in this regard, which I believe

is a rather severe no-no!!!

Having said that, there is something else that pisses me off about this

laser.
It's that asinine duty cycle recommendation -- the instructional

material states the following (in typical "Chinglish" -- no changes to

grammar or syntax were made):

"It is suggested that continuous working time never more than 30

Seconds,
" {yes, a comma and not a period). No "cooling" (off)

period is shown; though I would presume that it would be no less than 1

minute (60 seconds).

Does this eval. look an awful lot like the one I made for

this laser?
Thought you'd say so.
That's because they appear to be optically and electrically identical;

differing only in case color. So I was able to use its evaluation as a

template for this one.





Photograph of the "business-end" with the collimating ass'y removed.
That shiny toridial (doughnut-shaped) thing is the front face of the

laser diode.



Beam terminus photograph of this unique (well, "not-so-unique"

now) laser on the target at 12".
Beam image bloomed ***SIGNIFICANTLY*** even though it was

daylight when the photograph was taken. That white color does not

actually exist.
"Not no way, not no how" as they say.



Beam terminus photograph of this laser on the target at 12";

collimating lens removed.


Beam terminus photograph on a wall at ~10'.
That white color does not really exist, and beam image bloomed a bit.

This is a nonsmoking household and nothing was on the stove when this
photograph was taken, so I'm a bit surprised that the camera caught the
actual beam (it's not all that visible in this case, but you can see it
coming from the left of the terminus if you look).



Beam photograph with laser itself positioned approx. 9 feet downrange.



Short-term stability analysis for 600 seconds (10 minutes).

I had been running a "balls to the wall" long-term stability analysis,

but the test got queered after the LPM and the computer somehow lost

the com link; and seeing how the laser temperature was so high, I

decided to not attempt to redo it.

Laser temperature was measured with a

CEM DT-8810

Noncontact IR Thermometer
at 117°F (37.22°C) when the test was

2,455 seconds (24.25 minutes) in progress during the test; which

self-terminated shortly thereafter.

In light of this, I have decided to perform narrowband spectroscopy of

it to check for wavelength drift; see below for results of this

analysis.



Photograph of this laser's beam in snowfall.
Photograph was taken at 5:58am PST on 01-18-12 in Federal Way WA. USA.




Power output with the collimating lens in place: 690mW.


Power output with the collimating lens removed: 891mW.
This shows that the lens housing is vignetting (cutting off) the beam;
this power differential is far greater than would be caused by merely
passing the laser beam through a lens.



After intentional ignorance of the duty cycle recommendation (powered

on for 5 minutes constantly): 817mW.



Spectrographic analysis of the laser diode in this product.
Wavelength appears to be ~445nm, which is ***WELL*** within

specification for the type of laser diode used in this laser.



Same as above; but spectrometer's response narrowed to a band between

440nm and 450nm.
This shows that the wavelength is in fact exactly

447.00nm and the spectral line halfwidth

is ~2.20nm.


Spectrographic analysis of the laser diode in this product; taken right

at lasing threshold.



Spectrographic analysis of the laser diode in this product; taken right

at lasing threshold; but spectrometer's response narrowed to a band

between 440nm and 450nm.
This shows that the wavelength is

445.85nm and the spectral line halfwidth

is ~1.65nm.



Spectrographic analysis of the laser diode in this product; taken just

below lasing threshold.



Same as above taken just below lasing threshold; but spectrometer's

response narrowed to a band between 420nm and 470nm.



Spectrographic analysis of the laser diode in this product after five

minutes of continuous opertion (intentionally ignoring the duty cycle

recommendation of 30 seconds on, 60 seconds off for cooling). Exterior

temperature of the laser head after this test was 123°F (50.55C°);

ambient temperature was 69°F (20.55C°)



Same as above; but spectrometer's response narrowed to a band between

445nm and 450nm to pinpoint wavelength, which is 447.30nm. Spectral

line halfwidth is ~2.20nm.
Wavelength drift was only 0.30nm longer -- somewhat less than expected.



Spectrographic analysis of the laser diode in this product after

approx. 25 minutes of continuous operation to check for wavelength

drift; spectrometer's response narrowed to a band between 444nm and

449nm to pinpoint wavelength, which is 446.247nm. Spectral line

halfwidth is ~1.42nm.



Spectrographic analysis of the laser diode in this product; newest

spectrometer software settings used.

very likely figure out who the victor is here...





If you guessed "the laser" then ¡¡¡PARA NO DE LOS MOTIVOS DE CRISTO!!!

The heli wins this one!!! :-D

TEST NOTES:
Test unit was purchased from

DinoDiorect.com on 06-08-11 (or

"08 Jun 2011" if you prefer) and was received at 3:07pm PDT on 06-28-11

(or "28 Jun 2011").



UPDATE: 07-04-11
The "starfield projector" from the

Dapper Stage Laser Light

Show
screws into and fits this laser if the thin white toroidal

(doughnut-shaped) "sticker" over the output aperture is removed.

To wit:

This is the laser with the starfield projector affixed to the end.


This is a photograph of but one of many patterns that can be generated.




And this is a video on YourTube showing a holographic starfield

projector actually in use on the 1000mW 447nm Waterproof Adjust Focus

Blue Laser Pen. The starfield projector from the Dapper Stage Laser

Light Show properly fits & screws into the laser aperture -- which does

indeed have a female threaded receptacle that this starfield projector

fits. The patterns change as I slowly rotate the starfield optic

clockwise (as though tightening it) -- it is actually designed to be

used in this manner.

That music you hear is the song "The Voice of Energy" by

Kraftwerk. This laser is not

sound-sensitive; the audio may be ignored or even muted if it pisses

you off.

This video is approximately 9.30147438955 megabytes (9,494,079 bytes)

in length; dial-up users please be aware.
It will take no less than forty seven minutes to load at 48.0Kbps.


UPDATE: 07-20-11
This is the "sticker" being removed so that the holographic "starfield"

projecting heads from other laser products will fit.





PROS:
Color is very radiant & unusual for a handheld laser
The price is right!
Uses a rechargeable power source; never have to purchase disposable

batteries for it
Can directly use the "5 in 1" effects head that is commonly found on

other lasers



CONS:
***SERIOUSLY*** underpowered; it is advertised as being a 1 watt laser
Shorter-than-expected duty cycle recommendation (published at 30 sec.

"on"; no "off" time stated).
No safety features required of a CDRH Class IV laser -- this is by far

what nocked the most off of its rating!!!

Re: Review of the 1000mW 447nm Waterproof Adjust Focus Blue Laser Pen

thank you very much 4 the review.... i was looking it for a while!! no one reviewed this kind of LASER...... i think it is a good laser at the price.

rayfoss sell it at 180$.. but i found that the price of dinodirect it the best ever seen for a PREbuild 445nm laser..............
123$ is very nice.

i only have 1 question ..... did you try to leave the front circular WHITE hole?
i heard that if you remove it..... under it there are the screws to put the classic 5 in 1 effects.......... it would be nice if you can confirm it.........

and.... what about the BEST MRAD you can reach? is it under 2.. or 1.5 mrad?

Re: Review of the 1000mW 447nm Waterproof Adjust Focus Blue Laser Pen

Thanks for the review.

Also have this laser, review soon!

IMO a big + is that the laser is waterproof, haven´t tested it under water yet, cause I´m waiting for my underwatercam replacement right now. Just in case it isn´t waterproof, I want to film it dying :evil:

Re: Review of the 1000mW 447nm Waterproof Adjust Focus Blue Laser Pen

seemd that oklasers IS the supplier of rayfoss and olike... it have the same lasers that these shops sell.

i am interested in THIS laser
445nm 1000mw focusable burning blue laser pointer with star cap and key lock - 445nm-450nm blue laser - Blue Laser Pointer - Laser Pointers Catalog - Blue, Red, Green Laser Pointer, Powerful Lasers - OXlasers China


inTHIS PRECISE PIC http://img.diytrade.com/cdimg/925334/17631763/0/1291530922.jpg
i can see that in the 4th pic .. the front head that do STARS.... in reality "seems to be" a normal 5 in 1 head.... with an EXTERNAL BLACK adaptes...... but for reality i think it can accept EVERY 5 in 1 head.... nice!!!

i really want my first 445nm laser... my i am a strange boy.. i prefer MOMENTARY ON press button. i hate switch on and off laser...... i find that they are not so safe.. and not so easy to play with.....

this seems to be the only one 445nm boiuld with a momentary on button

You're more than welcome -- it was my pleasure to do this!!! :)



i only have 1 question ..... did you try to leave the front circular WHITE hole?
i heard that if you remove it..... under it there are the screws to put the classic 5 in 1 effects.......... it would be nice if you can confirm it.........
The end cap in mine is solid if the white thing (a rather thin, toroidal sticker is essentially all it is) is removed. No screws or other fasteners of any type are evident under the white ring.
To wit:




and.... what about the BEST MRAD you can reach? is it under 2.. or 1.5 mrad?
I do not have an instrument for measuring beam divergence; this neighbourhood is too densly populated to allow for any significant outdoor "shooting" as well...I'm afraid that divergence testing will have to be left to somebody with a larger outdoor arena and the proper mathematical formulae & measuring instrument(s), sorry about that.

Re: Review of the 1000mW 447nm Waterproof Adjust Focus Blue Laser Pen

.... but i see.....there are a sort of thread... where to put an optics. am i wrong?

i see it by picture..... i think that hole... allows to screw this http://www.laserlands.net/media/cat...8d6e5fb8d27136e95/5/3/532p-20-6in1-yh_3_3.jpg

Closer examination did in fact reveal a threaded female receptacle that the holographic "starfield" generator from the Dapper Stage Laser Light Show screws properly into.


This is the Dapper Stage Laser Light Show (I have a review of it on this BBS).


This is the laser with the Dapper's starfield projector affixed to the end.


And this is a photograph of but one of many patterns that can be generated.

I made a video showing the starfield generator in use; I'll be updaating this laser's review with that video tomorrow morniung. :D

You should shoot down your S107 with an IR laser :evil:

Did you test your Dino if it is waterproof?

I must agree with Jerry, you do some very awesome in depth reviews!

What do you do with all of these lasers you review? Do you resell? Or do you have hundreds of lasers!!???

I just attempted that very thing, and was ***NOT*** successful. :eek:

Yes I did, and yes (to the shallow depth that I can test to) it is.
To wit:



Waterproofness is as advertised: The tailcap, bezel, and barrel all held a good partial vacuum when they were suctioned (the tailcap held the vacuum even while the switch was actuated a number of times); there are O-rings present at both ends of the barrel as well.

I'm extremely pleased to find that you really like my reviews -- and that goes for the rest of "yous" "alls" too!!!


As far as the final disposition of the lasers that I test and evaluate, the vast majority of which aren't "loaners" are retained -- not only for future analyses and comparisons, but to just plain use as well!!! :) :D :)
Yes, I have quite literally hundreds of things that emit coherent electromagnetic radiation in the range of 402nm to 1,342nm.

This is fantastic news!!! :D
I'm going to add it in the "Pros" section of both of my 445nm lasers because you're not the only person who enjoys effects like this. :)
