    Question Lasers in freezing temps

    Does anyone know if it is harmful to a Crimson Trace laser (or any other laser) to be left locked up in a car during freezing weather? Will cold temperatures have any negative effect on the laser?

    Thanks

    Green lasers won't work below 30°F. Red lasers will. LaserMax says the low temps, i.e. even 10° and probably lower, won't hurt a laser. However they said below about 40°, a green laser simply won't come on. Viridian says 30° is about the limit for operation of a green laser.

    Many batteries behave poorly after extended cold,
    but that's a "battery that powers your laser" issue rather than an issue with the laser
    diode itself.
