    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 30F. 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.
