Zinc selenide optics for medical lasers by Laser Research Optics

A line of laser-grade zinc selenide (ZnSe) optics from Laser Research Optics (Providence, RI) can be fabricated to specification in 0.5 and 0.75 in. sizes for medical lasers. The optics can be supplied with dual-band and reflectance coatings up to 95% on each side. Optimized at 1064 nm for Nd:YAG lasers, the ZnSe optics include plano-convex and plane-parallel discs, output couplers, and mirrors. Featuring 40-20 scratch-dig surface finishes per MIL-O-13830 (20-10 one face on plane-parallel), the optics exhibit 1/4 wave at HeNe flatness and surface accuracy at 10.6 µm, with 3 arc-min maximum parallelism.
