PROVIDENCE, RI -- (Marketwired) -- 10/01/13 -- Meller Optics, Inc. has introduced custom manufactured low order sapphire waveplates that provide superior wear- and chemical-resistance while changing the polarization state of lasers.

Meller Sapphire Waveplates feature Moh 9 hardness, which is second only to diamond, allowing fabrication in sizes from 10 to 30 mm in either "A" or "M" plane configurations and are A/R coated on both sides. Highly resistant to chemicals, scratching, shock, and temperature fluctuations, these robust low order waveplates can be custom made as thin as 0.4 mm and < 25 mm dia.

Ideal for changing the polarization state in high power IR and visible lasers from linear to circular and vice versa, Meller Sapphire Waveplates exhibit 10-5 scratch-dig surface quality, < 1.0 arc/sec. parallelism, and they provide LAMBDA/4 and LAMBDA/2 retardation with tolerances of > LAMBDA/300 @632 µm, > LAMBDA/400 @1.06 µm, and > LAMBDA/1000 @2.94 µm. Single crystal quartz waveplates are also offered.

Meller Sapphire Waveplates are priced from $350.00 each, depending upon size and quantity. Price quotations are available upon request.
