This auction is for a Coherent Laser fold mirror for a frequency doubled argon laser at 244 nm, part# 7612-001-PV.  It is 1/2" diameter by 1/8" thick fused silica. It is designed to be a flat high reflector at 244nm at 45 degrees, though it probably works a bit on either side of that wavelength.  

Pick up a spare mirror for your laser or your lab at a small fraction of the new cost.

This optic is brand new in the original plastic container.  As you probably know, Coherent manufactures some of the best quality laser optics around, and you won't be disappointed with this optic.
