hey guys, quick question, I’ve got a cracked mirror, but was able to rotate it so the laser is not hitting the crack.
which type of mirror is better to get? Si or Mo mirrors? i can get a set of 3 off ebay, but not sure which are better.
I would say Mo as they tend to be more robust.
Anything is better than K19 :). Si is slightly more reflective but as mentioned before, doesn’t last as long.
