I am currently building a beamsplit system with a green diode laser and require a small (5mm x 5mm) mirror. I am not very versed in mirrors/optics, so I was wondering how much of the beam integrity will be lost in an aluminum or gold first surface mirror versus a regular first surface laser diode mirror. Apparently, it is pretty difficult to find a first surface mirror in the size that I am looking for. Here are the links at the two products. Ideally, I would like to have a normal mirror in 5mm x 5mm. But if the aluminum or gold will be fine without losing the beam quality, I can live with it.
