Sapphire Waveplates for High Power IR

Custom manufactured ultra-precise low order sapphire waveplates that extend polarization control into the infrared for high power IR and visible lasers are available from Meller Optics, Inc. of Providence, Rhode Island.

Meller Sapphire Waveplates change the polarization state of a laser beam from linear to circular and vise versa to extend polarization control into the infrared; beyond fused silica optical waveplates. Custom manufactured in sizes from 10 to 30 mm in “A” or “M” plane configurations, their crystal-lographic orientation and location are fully validated on an in-house X-Ray Goniometer to assure the highest possible accuracy.

Featuring Mohs 9 hardness which is second only to diamond, Meller Sapphire Waveplates are highly resistant to chemicals, scratching, shock, and temperature fluctuations. Manufactured as thin as 0.5 mm and < 25 mm dia. with transmitted wavefront of up to λ/10 @6.32.8 nm, they are A/R coated on both sides and provide λ/4 and λ/2 retardation with tolerances of > λ/300 @632 µm, > λ/400 @1.06 µm, and > λ/1000 @2.94 µm.

Meller Sapphire Waveplates are priced depending upon size and quantity. Literature and quotations are available upon request.
