Hi Everyone,
Looking for a "good" 25mm diameter pass green reflect red dichroic filter. The one I currently have (purchased on ebay) seems to leak a lot of green and quite a bit of red. Only one side of the optic seems to be coated, maybe that's my problem. Anyway, I'm looking to get something better. A scratched or nicked optic would be okay as long as the center, 5mm dia or so is still good. Worst case scenario I'll buy one from Edmund for $47.00. Are they any good?
Thanks!
Adam
