Null tested & figured and then tested via interferometry to insure the highest quality. These optics are (replace with were) painstakingly hand corrected to exacting tolerances, truly a labor of love. Please inquire for current delivery schedule. (Available for almost immediate delivery, just need coatings).

Enhanced aluminum coatings and securely boxed/crated. The Zerodur mirrors are "one of a kind" and only one of each is being offered for sale. I need to move this material and I will consider all offers and trades.
