High power invisible 30 milliwatt infrared laser at 980 nanometers operates on 3 volts (such as 2 AA batteries, or a 3V wall adapter; spring is "-", brass housing is "+"). This module is a Class 3B device and requires protective eyewear when viewing the beam or any potential direct reflections or scatter. Intended for experimental use in window bounce systems, target designation, optical x-rays, IR holography and general optical research. The module may be temporarily powered with just a 3 volt battery pack. Module measures ½” diameter x ½” length (or 1-1/4” length including pcb, or 1-3/4" length including pcb and spring) and includes a built-in adjustable collimating lens within the brass housing (adjustable with a wide-head phillips screwdriver). Excellent value, also includes our instructions on how to build a fully compliant Class 3B laser system.
Eye Protection: our OLY-LSG-1 protect against this wavelength. Always exercise great caution when using any high-power laser.
