Sale Prices Effective 4 Feb 2012

The mirror optics in the table below are premium mirrors. They are either partially finished or as shown under "condition" column. They are discounted because most are the previous-generation Pyrex which I obtained earlier at then-prevalent wholesale prices. They are guaranteed to perform to the same criteria as other premium mirrors I have made in the past. Depending on the state of completion shown in that column below, they can be finished in less time than new lots of mirror blanks, as there is no lead time involved to acquire them, plus they have undergone some degree of processing already. This further lessens time to completion. These are mostly traditional Pyrex borosilicate substrate, except as otherwise shown under Notes. All mirrors have an unconditional warranty for 90 days, and I will refund your payment in full if you find it does not meet your expectations. Each mirror is supplied with serialized certificate noting wavefront peak-valley, RMS and Strehl error, with detailed explanation of test results.

Payment - Make checks payable to Pegasus Optics. If you pay through Paypal, please include 3% Paypal fee equal to purchase price times 3%. We cannot directly debit your account using your credit card at this time.

*Sale price includes 95% IAD coating with quartz (SiO2) overcoat. For 98% add $50.

**Float glass is not an inferior grade of glass, and its thermal properties are not a relevant performance issue.
