    Default 20mm PBS cube, 488nm but works perfectly at 445nm, sale or swap for 638nm PBS

    I have an unopened 20mm PBS cube, it's coated for 488nm but I've tested another and it works perfectly at 445nm. I need a PBS for 638nm, so I'll swap this for a good 1/2" to 20mm PBS for that wavelength. Looking for UKú45 or US$65 or swap.

    I'll probably buy my red PBS cube from Rob if no one has one to swap.
