Was going to use this to build my own custom IR pointer w/ rail and barrel mounts but don't have time to do so. I've only used a CR123 lithium battery to test/confirm the IR beam.
Here's the spec on the IR laser diode that's For Sale (IR laser diode only):
It is new, never assembled OEM unit w/ bare wire leads:
Dimensions: 1.200" Length, 0.476" diameter of body, with about 4" of wire leads
Aperture: threaded on the outside diameter and adjustable IR lens (width of point).
Wavelength: 980nm IR
Power output: 36mW
Power source: 3V
Mfg: Has label confirming the spec but no manufacture on it. It is very well, solidly built unit.
SOLD CONUS Priority Mail w/ del. confirmation.
Payment via Postal MO or PayPal (+ 3.5%). Email direct any questions and for pictures.
