calcium fluoride lens is an excellent material for ultraviolet to near infrared wavelengths (180-8000 nm). Compared with various infrared materials, it has higher average transmittance and lower color difference. In the near-infrared range, its GVD is very low, so it is very suitable for some applications that need to use femtosecond infrared pulse.

coated ZnSe plano-convex lenses are designed for use as focusing lenses for high power CO2 lasers. They are manufactured by automated CNC technology and designed for highest durability and accuracy, assuring complete uniformity, repeatability and consistency.

MgF2 Achromatic lens is made by gluing two single lenses. The product is optimized by computer to reduce the spherical aberration and chromatic aberration on the axis. Single layer MgF2 film or broadband antireflection film can be selected. NIR achromatic double glued lens and edge blackening version can also be selected. All dimensions are in mm.

245-440 nm antireflection coating of UV grade fused silica Plano convex lens is used to meet the stringent requirements of laser electro-optic focusing. These lenses are polished using the master test plate to achieve tight tolerances, ensuring minimal wavefront distortion. Its strict surface quality tolerance minimizes scattering and harmful diffraction effects.

Chemically vapor deposited CVD Zinc Selenide is the material of choice for use as optical components in high powered CO2 lasers due to its low bulk absorption at 10.6 microns. Its index of refraction homogeneity and uniformity offers excellent optical performance for use as protective windows or optical elements in high resolution forward looking (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.
CVD Zinc Selenide is chemically inert, non-hygroscopic, highly pure, theoretically dense and easily machined. It has extremely low bulk losses due to absorption and scatter, has a high resistance to thermal shock and is stable in virtually all environments.
Custom diameters, rectangles, CNC-profiled blanks, generated lens blanks, prisms and near-net shape domes can be made to your specifications.

CVD Ceramics' chemically vapor deposited CVD Zinc Sulfide is the low cost alternative for infrared windows, domes and optical elements. With a fracture strength double that of zinc Sulfide and high hardness, zinc sulfide has been used successfully in many military applications requiring mechanical resistance to hostile environments. Cleartran is a form of CVD Zinc Sulfide material that is modified by a post-deposition hot isostatic process. This process removes zinc hydrides from the crystal lattice, normalizes crystal structure and purifies the material, all contributing to single crystal-like transmittance in the visible through far infrared ranges (0.35 -14 microns). With its low absorption and scatter throughout its broad transmitting range and high optical quality, is particularly well-suited for multi-spectral applications that require a single aperture for beam path for several wavebands.
