I have 6 of these mirrors which pass Blue and Green and reflect Blue, I also am including 4 FS mirrors.
These are pulled from a TV Projector that we are all used to by now. One FS and one Dichroic have very very minor chips in the corner. Still perfectly usable.
I am selling all these mentioned here for $50 shipped in the US. Add $20 for international shipping.

9V not included.
