Optical Materials
ZnSe
CVD ZINC SELENIDE Material is the material of choice for optical components in high-powered CO2 lasers due to its low bulk absorption at 10.6 microns. Its index of refraction, homogeneity and uniformity offer excellent optical performance for use as protective windows or optical elements in high-resolution forward looking infrared (FLIR) thermal imaging equipment. This material has also been used as small windows and lenses in medical and industrial applications, such as thermometry and spectroscopy.
ZnS Multispectrum
ZnS MultiSpectral is infrared’s zinc sulfide material treated by a hot isostatic press (HIP) process. Under intense heat and pressure, defects within the crystalline lattice are virtually eliminated, leaving a water-clear material with minimal scatter and high transmission characteristics from 0.4 to 12 microns. This material is particularly well suited for high-performance common aperture systems that must perform across a broad wavelength spectrum.
ZnS
Zinc Sulfide is a polycrystalline optical material with high performance in fracture strength and hardness. ZnS is often used in the 8-12µm region. Its resistance to rain and particle erosion coupled with its lower relative cost provide ZnS with an edge over ZnS-MS and ZnSe in many applications, such as IR windows for military systems
Germanium
Germanium is a strong and durable material with high refractive index. One of its many advantages is also its versatility which allows it to be shaped into variety of shapes and sizes. Due to its high refractive index it is widely used in thermal imaging applications.
Silicon
Silicon is rather hard material, resistant to many external constraints and excels in thermal stability. As it is the half of density of germanium, it is ideal for weight sensitive optical applications. Our company is able to supply ,besides others, monocrystalline float zone silicon in purity of > 99,999%
Chalcogenide Glass
Chalcogenide glasses includes compositions designed to transmit in short to long wave ranges delivering an improved optical performance and reduced thermal sensitivity when compared to traditional materials on the market thus achieving both a cost-effective and customizable option for thermal imaging applications per the specifications.
Fused Silica
This high purity Fused Silica with excellent optical qualities such as extraordinary low refractive index excellent homogeneity values, lowest birefringence values, exceptional transmittance from the deep ultraviolet through the infrared region, and an ultra-low thermal expansion coefficient.
Sapphire
Sapphire excels in optical applications that require reliability, strength and a wide range of light transmittance. Sapphire transmits in the UV, visible, and near infra-red. The wavelength range spans from 0.15 to 5 microns. This unique ability to transmit over a broad range combined with its mechanical strength makes sapphire the material of choice for many space and military applications.
Zerodur (Schott)
ZERODUR® is a glass ceramic with an extremely low thermal expansion for demanding applications in which geometrical shape and distance changes must kept smallest possible under temperature variations. It is ideal for a vast range of applications that rely on exceptionally low thermal expansion materials. It's also now the industry standard for ultra-precise mirror substrates in astronomy.
Tellurium dioxide (TeO2)
TeO2 crystals are the most effective material to make components for laser beam controls to change their characteristics.
Devices with TeO2 blocks can be effectively and successfully used for signal modulation (AO Modulators), deflection (AO Deflectors) and selection (AOTF).
