ZnS Multispectral Optics for High-Power 1.0-µm Lasers

Water-clear zinc sulphide multispectral (MS) optics by II-VI Infrared are ideally suited to high-power 1.0-µm laser systems, and offer myriad advantages over traditional fused silica optics. Like II-VI Infrared’s world-renowned ZnSe optics, ZnS MS optics are diamond-turnable, and capable of being machined into aspheres, faceted beam integrators, and other advanced optical surfaces. Their higher index of refraction means lower spherical aberration for lenses. And greater thermal conductivity means less thermal lensing, enhanced focal length, and working distance stability. ZnS MS is II-VI Infrared’s own ZnS that has been post-deposition treated by a hot isostatic press process. Under intense heat and pressure, defects within the crystal lattice are virtually eliminated, leaving a water-clear material with minimal scatter and high transmission characteristics from 0.4 to 12 µm. This material is particularly well suited for high-performance single aperture systems that must perform across a broad wavelength spectrum.

GLOSSARY
aperture
An opening or hole through which radiation or matter may pass.
photonics
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
