Reflection Mirrors

[Knight]

Hi All,
I want to replace the Reflection mirrors in my laser cutter but I am not sure what the difference is with the different types that are available.

Do the different types have a different effect when fitted, does it depend on what is being cut or the laser power?

I want to cut MDF, Plywood (4mm & 6mm) and Acrylic. What mirrors should I look for? There are so many to choose from.

The original mirrors fitted to my laser had a golden coloured reflective finish but age and use has not been kind to them.

I did get a set of 3 with my upgrade parts, but they look like normal mirrors and with all the messing around I have been doing trying to align them, they have become a little scratched.

Any suggestions? (apart from try to be more careful with my mirrors).

Any information gratefully absorbed.

Thanks,
Regards,
Albert
