Featured inquiry:

I’m part of a team working on a spectrograph design for the Canada-France-Hawaii telescope (CFHT). The system will include ZnSe cross-disperser prisms and will operate at [0.98 – 2.4 microns] range.

What is the maximum diameter of ZnSe prisms you can make. Do you make blank or just machine them?
