(In reference to the small "bubbleope" I received from an Ebay seller around 2:22pm PST on 03-08-08):
{sung like the Foreigner song "Feels Like the First Time"}


This is a pointer-style laser module that emits just over 8mW at ~660nm in the red region of the spectrum.
Being advertised as a 650nm laser, the seller did fudge the wavelength rating a bit, but it's still within spec as diode lasers go.

Like many other "pointer"-style lasers, it comes in a metal body with what I believe is a baked enamel black finish, and feeds from two AAA cells held in its barrel.

* This module looks & works like a laser pointer, but it has an output of 8.29mW, which means I cannot call it a "pointer" on this website...unless I want to get into hot water with the CDRH (Center for Devices and Radiological Health, the government agency that regulates laser products in the United States) that is.


SIZE



Like most other laser pointers/self-contained laser modules, this product is easy to use.
Just 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 change the batteries in your red laser module, unscrew and remove the tailcap, gently place it on the ground, and kick it into the garden so the hungry, hungry praying mantids will think it's something yummy for their insect tummies and subsequently strike at it...O WAIT!!! YOU'LL NEED THAT!!! 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 (rechargeables only!!!) as you see fit.

Insert two new or freshly charged 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 tailcap back on, and be done with it.
Aren't you glad you didn't kick that tailcap into the garden with all those hungry, hungry praying mantids now?


Here is what a praying mantis looks like.
I found this guy on the morning of 09-08-06 clinging to the basket of my scooter.

Current usage measures 27.1mA on my DMM's 400mA scale.



This is a laser (or "lazer") module, not a flashlight meant to be thrashed and abused, so I won't throw it against the wall, stomp on it, try to drown it in the {vulgar term for feces}bowl or the cistern, run over it, swing it against the concrete floor of a patio, bash it open to check it for candiosity, fire it from the cannonada (I guess I've been watching the TV program "Viva Piņata" too much again - candiosity is usually checked with a scanner-type device on a platform with a large readout, with a handheld wand that Langston Lickatoad uses, or with a pack-of-cards-sized device that Fergy Fudgehog uses; and the cannonada is only used to shoot piņatas to piņata parties away from picturesque Piņata Island), send it to the Daystrom Institute for additional analysis, or inflict upon it punishments that I might inflict upon a flashlight. I generally don't punish lasers or most other products which lase. So this section of the web page will be rather bare, when compared to this section of the web page on a page about a flashlight.

This evaluation look an awful lot like the one I made for the 5mW* 650nm Red Laser Module?
Thought you'd say so.
They're virtually identical to one another, so I could use its web page as a template for this one.

Same as above; spectrometer's response narrowed to a range of 645nm to 665nm.
The spectral line halfwidth is ~3.5nm.
