Review of the 1mW 405nm Blue Violet Laser MODULE Military Exclusive

The 1mW 405nm Blue Violet Laser MODULE Military Exclusive (hereinafter, just called a "Blu-ray Laser Pen") is a violet-emitting, directly-injected laser. That is, it produces violet laser radiation directly, without the need for messy, fragile nonlinear crystals like those green laser pointers and the amberish-yellow and blue ones as well. It uses two AAA cells -- the same power source used in most other "pen-style" laser pointers and laser modules.

It is advertised to output less than 1mW of laser radiation at ~405nm.
It actually measures 19.00mW at 404.65nm!!!

This is the reason I call it a "module" on my website (and in this post) instead of a "pointer". Lasers designated as "pointers" must -- by US law anyway -- have a power output that does not exceed 5mW.

It comes in a handsome brass body with a black finish and chrome colored bezel, tailcap, and pocket clip.

SIZE



To get the laser to turn on, first be certain that there are a pair of AAA cells installed. If there aren't, then install them (see directly below), and THEN you can go irradiate something.

Aim the laser well-away from your face first. Press & hold down the button on the barrel for as long as you want or need the laser spot, and release pressure on the button to turn the laser back off.




To change the batteries in this violet laser , unscrew & remove the tailcap, and set it aside.

Tip the two used AAA cells out of the barrel and into your hand, and dispose of, recycle, or recharge them as you see fit.

Insert two new AAA cells 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 of the tube back on, and be done with it.

Current usage measures 114.70mA on my DMM's 400mA scale.



***EXTREMELY IMPORTANT!!!***
This laser has a fair amount of {vulgar slang term for male nads} to it (measured at 19.00mW), 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.

Does this evaluation look an awful lot like the one I made for this laser?
Thought you'd say so.
That's because they're functionally identical, so I was able to use its web page as a template for this one.



TEST NOTES:
Test unit was purchased on Ebay on 05-01-11 (or "01 May 2011" if you prefer) and was received at 3:47pm PDT on 05-10-11 (or "10 May 2011").

I have decided to rate this wonderful little laser four stars!!!
If something happens down the road, I can always derate it if necessary.




UPDATE: 00-00-00


PROS:
Color is very radiant & unusual for a handheld laser
Uses inexpensive and readily available batteries
The price is right!
Color is very radiant an unu...o wait, I said that already!!!


CONS:
Just the usual suspects for laser modules/pointers - nothing that affects rating...actually, there is one little thing: it is advertised as a <1mW laser (and has a CDRH Class II warning label on it), but outputs 19mW of laser radiation.
That's what lopped that last star off.

Nice review +1, but isnt it kind of expensive for just 19mw ?

Yeah seem $$, not a special host or anything like that

Click to expand...

First off, thank you for the +1 rep -- much appreciated!!!

Now, to the crux of the matter here...expensive, perhaps a bit.
But remember that not that many years ago, the Wicked Lasers Sonar sold for almost $2,000.00 and it had an average power output of just 2.897246mW (it was pulsed at approx. 265Hz if I remember correctly, and had a duty cycle of 16.67%).

Wow I never knew that it was that low in ouput.
