Is this laser any good?






Looks sketchy a new member with no history at all.
Error "532nm" in description. Hm......
Good luck, I guess...:thinking:
 
I noted the description error -- I chalked it up to human error under the assumption that this person has handled mainly 532nm DPSS lasers until just recently...but you know what they say, "When you assume, that makes an ass out of you and me." :eek:

There is one that is essentially the same laser on dinodirect for $50 less.
1000mW 1W 447nm Waterproof Adjust Focus Blue Laser Pointer Pen (1 x 18650 Battery) - DinoDirect.com

I just purchased that one; presuming it ships to the US alright, I'll compare them both. :)

Everybody on Ebay was a newbie at one time...I've decided to give this seller the benefit of the doubt in this case.
 
Nice! I was curious about that one I linked. Looking forward to your eval.

A good review you'll get too -- I also purchased a LaserBee LPM that can "do" up to 2.50 watts -- so I'll have power measurements on them -- plus my pair of Arctics as well!!! :umbrella:

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


445-4-4.gif

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.

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.



445-4-2.gif

Same as above; but spectrometer's response narrowed to a band between 400nm and 410nm.
This shows that the wavelength is in fact exactly 447.00nm and the spectral line halfwidth is ~2.20nm.

My full review will be posted on this BBS probably sometime tomorrow morning.if[/img]

This is the DinoDirect one? Man why can't these guys delivery their rated output. Such a shame. It is a pretty cool laser in almost every other way. I would love one of these at 1.2W

Yup, this is indeed the DinoDirect one.
I did remeasure both lensed and unlensed power output with a different battery and got slightly higher readings, but still not the 1W that was advertised. :(
 
Nice!...well sort of depending on ur point of view, $123 for class IV 445nm laser is still not that bad and it is a 18650 host, which personally i like more than using 2xcr123.

Ill check out ur review tomorrow!... is the host blue colored as depicted in the pics?

2x CR123 or 2x 18350's even 2x 18650 (if you dont mind the length..)
make for better lasers.. I say this because when used with a buck driver,
there is no heat added to the laser and less current is drawn from the batteries.

Most boost circuits that ive tried tend to generate plenty of wasteful
heat when upward of 1.5A+.

A buck driver putting out 1.5A or more do not need thermal epoxy
nor additional heatsinking. Thats a win in my books :san:



Guess its preference :whistle:
