These are small, pre-wired red diode laser modules. That is, they already include the optics assembly, and they're ready to connect to any source of 3 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 a closed circuit output of 3 to no more than 4.5 volts DC and can deliver at least 25mA.
They come prepped with power wires, approximately 5.25" (~14.50cm) in length.

The laser module (either one) is ready to go as soon as you receive it.

The Aixiz one has adjustable focus; the Steiner & Martins one has focus fixed at infinity.


Size of product w/hand to show scale SIZE



To use the laser module, just connect it to any source of 3 to 4.5 volts DC via the included wires. Red is (+) positive, white is (-) negative.
There is no on/off switch; if you wish to use one you will have to supply and connect it yourself.

The Aixiz module has an adjustable focus ranging from very narrow spot to medium spot; just rotate the "business-end" of the laser module one way or the other. If you unscrew the end all the way until it comes off, be careful not to let the small spring shoot out unnoticed and later fall prey to the hungry, hungry vacuum cleaner (yes, the spring in one of the Aixiz modules flew out unnoticed yesterday {02-11-09}; the telephone technician found it on the floor under the desk when he was working on the telephone jack in my room!!!)




Because this device runs from any source of 3 to 4.5 volts DC, this section will contain very little additional information.
Just connect it to your chosen power source so that the red wire goes to the (+) positive, and the black wire goes to the (-) negative.

Current usage measures:

19.3mA (Aixiz)
14.7mA (Steiner & Martin)

Both measurements were performed on my DMM's 400mA scale.
This is with a Vf of 4.49 volts (closed-circuit, not open-circuit), using an Aixiz laser diode module power supply unit specifically made for this application.



Because this is a component designed to be installed in something, and not a flashlight meant to be carried around, thrashed, trashed, and abused, I won't try to drown it in the toliet tank, bash it against a steel rod or against the concrete floor of a patio, let my mother's dog's ghost take a leak on it, run over it with a 450lb Celebrity motorised wheelchair, stomp on it, use a medium ball peen hammer 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), send it to the Daystrom Institute for additional analysis, or perform other indecencies on it that a flashlight might have to have performed on it. So this section of the web page will be ***SIGNIFICANTLY*** more bare than this section of the web page on a page about a flashlight.

Yes, that large dim red "blotch" you see near the top of
this photograph is an artifact produced by the laser itself.

TEST NOTES:
Test units were furnished for spectroscopy and power output measurements by J.G. and were received on approximately 02-08-09.

The Aixiz laser module was made in the United States, and the Steiner & Martin laser module was made in an unknown country.
A product's country of origin really does matter to some people, which is why I published it on this web page.
