    Default Mirrors

    I bought a couple of these guys the other day from EO.
    Does anyone know if they'll have a problem handling 400mW (Marconi's) ?
    Thanks in advance

    I think no problem, you will only have heating problems when the power reach >10 watts
    If they reflect 95% of the beam (and normaly a good laser mirror is >95%), only 20mW will be absorbed...

    For my red I found a good deal on Ebay for 5-10$, they reflect only red but I measured no power loss, max 1mW for 200mW

    Thanks Sbk
    ..actually they're spec'd at about >97%
    I see what you mean about absorbtion though.
