Mirror in OHP - Click HERE for Original Thread
tetutigre
Hi,

Simple question... is the mirror in an OHP a "cold mirror"? I've got a non working 3m 9050 and would like to find out before I buy one at surplus shed. Thanks

I believe mirrors from OHP's are just front surface mirrors

i've got a dead 3M overhead with a trapezoid shaped front surface mirror and a few Apollo Eclipse overheads that are missing their front surface mirror above the condenser.

so, does this mean I can cut a mirror from the 3M overhead and replace my Apollo mirror?
