Yes but I¹m sure the formula calls for two optically flat surfaces; perhaps
a specified thickness.
Gee could not just the right coating screw it up?

Zeiss in the form of Heliopan Schott glass wont be able to gladly fill the
bill and one of them were probably already making them for Hasselblad in the
