Keychain-Style Portable Laser (3), retail $TBA
Manufactured by (Unknown)
Last updated 11-23-12

What this is is a keychain-style laser pointer that can be stuffed in your pocket or live in your briefcase. It emits a red beam with approximately 17mW (measured) of output power.

It comes in a shiny silver body, and feeds from three LR44 button cells (the ubitiquous "laser pointer battery).

Because this is a laser, you should not shine it into your eyes, other people's eyes, pet's eyes, etc. Just use a little common sense here, ok?

The emitted wavelength was spectroscopically measured at 665.247nm, in the red portion of the spectrum.

SIZE

Point the front end at whatever you wish to point out, and hold the button at the top front of its barrel down for as long as you need the laser spot. Release the button to turn the laser pointer off.

Yes, it really is that easy.

This button has a tactile "click" sensation to it. This click may also be audible to the user in a quiet location.

To change the batteries in your laser, unscrew and remove the tailcap, throw it in the {vulgar term for feces}bowl, yank that silver handle on the front of the cistern down, and flush it away...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

Tip the three used LR44 cells out of the barrel and into your hand, and dispose of or recycle them as you see fit.

Insert three new LR44 cells into the barrel, button-end (-) negative first. This is the opposite polarity of batteries that are installed in most flashlights, so please pay attention to polarity here.

Screw the tailcap back on, and be done with it.
Aren't you glad you didn't flush away that tailcap now?

Current usage measures 24.490mA using the 40mA scale on my DMM.

This is a laser pointer, not a flashlight meant to be carried around, thrashed, trashed, and abused, so I won't try to drown it in the toliet tank, bash it against a steel rod or against the concrete floor of a garage, let my mother's citty kats

, my sister's cat, or my own little fuzzbomb go to the litterbox on it or my parent's dog's ghost lift his leg on it, run over it with a 450lb Celebrity motorised wheelchair, stomp on it, use a large claw hammer 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), send it to the Daystrom Institute for additional analysis, or perform other indecencies on it that flashlights might have to have performed on them. So this section of the web page about this laser pointer will be ***SIGNIFICANTLY*** 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.

This product is properly labelled as to its wavelength, but is improperly labelled as to its power output (it is labelled to output less than 5mW, but measured 17mW).

Power output analysis

Power output measures 17mW on a LaserBee 2.5W USB Laser Power Meter w/Thermopile.

Short-term stability analysis

Spectrographic analysis of this laser.

Same as above; spectrometer's response narrowed to a range between 663nm to 667nm to pinpoint wavelength, which is 665.247nm.
Its spectral line halfwidth is ~0.70nm, which (in my opinion) is slightly unusually narrow for a diode laser.

TEST NOTES:
Test unit was found on 11-13-11 while looking for another laser that required spectrocopy.
It was most likely obtained on Ebay or other similar venue within the last several years.

UPDATE: 00-00-00

PROS:
Handy size & shape
Appears exceptionally beefy & sturdy for a keychain laser

NEUTRAL:

CONS:
Improperly labelled for power output (***POOF!!!*** there goes at least one star)
