    Default Illumination supply - Laser power meter

    Was bringing out some old laser equipment along with my LPM and found that the actual LPM head has split in two, Never seen a peltier element of this type split like this in storage.

    seems to be a 10mm x 10mm by 2 mm thickness element. has anyone else seen these types of elements break like this?

    Would anyone happen to know the element used here and if it is just to replace with the same dimensions? I assume not as they would probably need to be the same wattage.

    Better off getting something new or try to repair? what do you guys say

    these are hard to find and not cheap but I would guess it is something like this, that product line has square ones as well.

    I have used a TEC from a dead laser as well, no clue on accuracy though. would be fun to try though
