Ultra-Slim Laser Pointer, retail $19.99 (www.radioshack.com...)

Last updated 03-22-12

This is a slim, handheld laser pointer. It comes in a matte finish silver plastic body surrounded by a black painted metal ring.

It operates from a single CR2025 lithium coin cell, produces a red beam, and has a rated output of less than 5mW, making it a CDRH Class IIIa laser device, legal for citizens of the United States to use in public.

The emitted wavelength appears to be 657nm, in the red portion of the spectrum.


The Ultra-Slim laser pointer comes ready to use right away.

Point the front end at whatever you wish to point out, and hold the button at the top front of its body 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 battery in your Ultra-Slim laser pointer, turn the laser upside-down, and look for the projecting piece at one end.

Using your fingernail, place it toward the back of the laser next to that projecting piece, push it toward the front of the laser, and lift the door off.

Remove the used battery, and dispose of or recycle it as you see fit.

Use one hand to hold the springy metal leaf in the battery compartment up approximately 0.10" (or the approximate thickness of a CR2025 cell) from the floor of the battery compartment, and use the other hand to insert a new CR2025 lithium coin cell in the battery compartment, button-end (-) negative facing down.

Once the battery is in there, reinstall the battery door by inserting the notched end (the end with the three little tits on it) into the laser pointer body, and then swing the door down and press on it firmly but gently until it fits flush with the rest of the laser pointer body and it snaps into place.

This procedure sounds significantly harder to do in print than it is to actually do it.

Due to the way the Ultra-Slim laser pointer is constructed, I am unable to measure its current consumption.

This is a laser pointer, not a flashlight. So I won't whack it against a steel rod, run over it, try to drown it in the toilet bowl, throw it, stomp on it, or subject it to other abuses that a flashlight might have to endure. So this section of the web page will be more bare than this section of the page on a page about a flashlight.

This product is properly labelled as to its wavelength and power output.

Test unit was purchased at a Radio Shack in Sacramento CA. USA late on the morning of 05-03-07.

Product was made in China. A product's country of origin really does matter to some people, which is why I published it on this web page.
