Sapphire Waveplates
Photonics Spectra
Feb 2017Meller Optics Inc. has announced Sapphire Waveplates that extend IR polarization control into the IR, beyond fused silica optical waveplates.
The devices feature Moh 9 hardness, making them highly resistant to chemicals, scratching, shock and temperature fluctuations. Designed to change the polarization state of a laser beam from linear to circular and vice versa in high-power IR and visible lasers, accuracy is assured by ultra-precise, in-house goniometric validation of their crystallographic orientation and location.
Offered in custom sizes from 10 to 30 mm in A or M plane configurations, the Sapphire Waveplates can be made as thin as 0.4 mm and <25 mm in diameter with transmitted wavefront of >λ/10 at 6.32.8 nm. They are antireflection coated on both sides and provide λ/4 and λ/2 retardation with tolerances of > λ/300 at 632 µm, > λ/400 1.06 µm and > λ/1000 at 2.94 µm.
