(In reference to the envelope I received in the mail on the morning of 10-16-08):
{sung like the Foreigner song "Feels Like the First Time"}


 This is a small, pre-wired green DPSS laser module that has a line generator optic built in. It's ready to connect to any source of 3 volts to 3.2 volts DC that you happen to have handy; whether that's a pair of 1.5 volt AAA or AA cells, a 3 volt lithium CR2 or CR123A cell, or a "wall wart" type AC adapter that you know has an output of 3 to 3.2 volts DC and can deliver at least 175mA.

It comes prepped with power wires, approximately 5.75" (~14.6cm) in length.

The laser module is ready to go as soon as you receive it.


SIZE



To use the laser module, just connect it to any source of 3.0 to 3.2 volts DC via the included wires. Red is (+) positive, black is (-) negative.

There is no on/off switch; if you wish to use one you will have to supply and connect it yourself. Connect the switch in series with the laser; hook up one lead to the laser's red wire; connect the other to the power supply (+) positive.



Because this device runs from any source of 3 to 3.2 volts DC, this section will contain very little additional information.

Current consumption measures 157mA at a Vf of 2.692 volts (a single CR123A cell was used for this and all other measurements on this web page).



Because this is a component designed to be installed in something, and not a flashlight, I won't do the smack test on it. I know you love to see me break things, but it "ain't" "gonna" happen today, folks. So I won't throw it against the wall, stomp on it, try to drown it in the toylet bowl or the cistern, run over it, swing it against the concrete floor of a patio, use a small sledgehammer in order to bash it open to check it for candiosity, fire it from the cannoņata, drop it down the top of Mt. Erupto (I guess I've been watching the TV program "Viva Piņata" too much again - candiosity is usually checked with a laser-type device on a platform with a large readout (located at Piņata Central), with a handheld wand that Langston Lickatoad uses, or with a pack-of-cards-sized device that Fergy Fudgehog uses; the cannoņata (also located at Piņata Central) is only used to shoot piņatas to piņata parties away from picturesque Piņata Island, and Mt. Erupto is an active volcano on Piņata Island {In the episode "Les Saves the Day...Again", Paulie Preztail says "Hey, ever wonder why this park's called 'Mount Erupto' anyway?", then Franklin Fizzlybear says "I think its an old native term. Means 'very safe.'"}), send it to the Daystrom Institute for additional analysis, or inflict upon it punishments that flashlights may have inflicted upon them. So this section of the laser's web page will seem a bit more bare than this section of the web page on a page about a flashlight that was born to be a flashlight and nothing but a flashlight.

The line generating optic does not appear to be a conventional (cylindrical) lens, but it does not appear to be a holographic grating either...
Is it possibly a cylindrical Fresnel lens?


Here's a photograph of the front of the laser.
Yes, I know that this photograph is furry; I made multiple attempts, and if you can believe it, this was the best one.

The beam (line) angle is stated as 110°; the line's width is stated as 2mm to 3mm at 1 meter.

Photograph was left deliberately uncropped.
Measures 7.140mW on a laser power meter.


Photograph on a wall at ~9 feet.
Line is not "bent" or curved like this photograph indicates.

Those rectangular graphic things in the upper right quadrant of this photograph are marquees from:

Sega ''Star Trek''
Atari ''Tempest''
Venture Line ''Looping''
Jaleco ''Exerion''

upright coin-op arcade video games from the 1980s.

And those colored graphics toward the left are my "Viva Piņata" posters.

Room illumination was greatly reduced for this photograph.


Spectrographic plot
Spectrographic analysis of this laser module.
Absolutely *NO* NIR (near-infrared) radiation from the pump diode was noted, not even when the spectrometer was deliberately "overloaded".

TEST NOTES:
Test unit was purchased on Ebay on 10-14-08, and was received on 10-16-08.

Unit was purchased from "Instapark" on Ebay, who has an Ebay Store where this and similar (laser & lighting) products can be purchased.
