This is a violet directly-injected laser module.

But what sets this laser module apart from most others you can get isn't that violet laser diode, and it isn't the AAA cells it feeds from. It's that moveable holographic diffraction grating optic on the unit's "business end" that allows it to project "stars" when the button is pressed, rather than just a single dot like most other laser modules. This grating can be rotated to project any of quite literally HUNDREDS of different patterns.

It comes in what I believe is a brass body.

* Price was for a 3-pack containing red, green, and violet units.

SIZE

Feed the laser module a pair of AAA cells that you furnish yourself (see below), and then you'll be ready to rock.

To use the laser module to point something out, unscrew & remove the diffraction grating tip, aim it at something you wish to point out, and press & hold down the button on the barrel for as long as you need the laser spot. Release the button to turn the laser module back off. Yes, it really is as easy as that.

To use the laser module as a "star" projector, do exactly as above except do not remove the tip. Rotate (turn) the tip clockwise (as though tightening it) to change the pattern of the projected "stars".

The laser module comes with a pocket clip, already attached. You know what it's for.
If not, slip the laser module into a shirt or pants pocket, and slide the clip over the outside of the fabric of the pocket when the module is being inserted into the pocket.

To change the batteries in this violet laser, unscrew the laser near the center, gently place the upper portion onto the floor in front of the stairs leading to the basement, and kick it down those stairs so that the piss ants with full bladders will think it's something to eat, find it unpalatable, drag it to the queen, who just sniffs at it, uranates all over it, and instructs the worker ants to do the same...O WAIT!!! THAT'S THE GOOD PART!!! So just set it aside instead.

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 front portion of the tube back on, and be done with it.
Aren't you glad that you didn't kick that front piece into the basement with all of those hungry ants that really had to piddle now?

Unable to measure current usage due to how the product was constructed.

This is a laser module, not a flashlight. 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 cannoñata

, drop it down the top of Mt. Erupto

(I guess I've been watching the TV program "Viva Piñata" too much again

- candiosity is usually checked with a laser-type device on a platform with a large readout (located at Piñata Central), with a handheld wand that Langston Lickatoad uses, or with a pack-of-cards-sized device that Fergy Fudgehog uses; the cannoñata (also located at Piñata Central) is only used to shoot piñatas to piñata parties away from picturesque Piñata Island, and Mt. Erupto is an active volcano on Piñata 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.

This laser is lightly splatter-resistant, but it is not water- or pee-resistant, so please be extra careful when using it around sinks, tubs, "terlets", fishtanks, pet water bowls, or other places where water or water-like liquids might be found. And you'll probably want to cover it up or otherwise get rid of it (such as by putting it in a pocket or bag) if you need to carry it in rainy or snowy weather.

Although the barrel is smooth, it does *NOT* feel at all slippery; the exterior finish feels almost a bit "rubbery" even though that's not what it is. I'm not exactly certain what the exterior finish is, but it has a somewhat "grippy" feel to it.

The diffraction grating can be easily rotated by hand, but it has a stiff enough "action" to it that it won't just spin by itself or through casual handling.

Beam is not white like this photograph makes it appear.
Beam is also somewhat smaller than it appears;
the beam image also bloomed ***SIGNIFICANTLY*** when photographed.

Power measures 60.030mW (w/diffraction grating removed) on a laser power meter designed for that purpose.

Power output was remeasured at 39mW on a LaserBee 2.5W USB Laser Power Meter w/Thermopile.

Beam is also somewhat smaller than it appears;
the beam image also bloomed rather substantially when photographed.

Spectrographic analysis of this laser; newest spectrometer software settings used -- spectrometer's response narrowed to a band between 395nm and 415nm to pinpoint wavelength; which appears to be 405.667nm.

Spectrographic analysis of the fluorescence of a uranated* glass marble when irradiated with this laser.

Spectrographic analysis of the fluorescence of the 2009 NIA commemorative insulator in uranated* glass when irradiated with this laser.

*"Uranated" - infused with an oxide anion of uranium, *NOT* piddled (peed) on.
Commonly referred to as "Vaseline glass" because it has
a distinct pale yellow-green color when not being irradiated.

Note spelling: "urAnated", not "urEnated","urInated",
"urOnated", "urUnated", or sometimes "urYnated".

Unit is improperly labelled for power output; that's what nocked that last star off its rating.

Projects a widely-varying starfield that's easily user-adjustable
Uses batteries that are common and relatively inexpen$ive

Incorrectly labelled for power output (labelled as CDRH Class IIIa <5mW); has a measured output of 60.030mW.
