IdealPhotonics 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 µm. 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 can also be 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.

Zinc Selenide is produced by synthesis from Zinc vapour and H2Se gas, forming as sheets on Graphite susceptors. Zinc Selenide is microcrystalline in structure, the grain size being controlled to produce maximum strength. Single crystal ZnSe is available, but is not common but has been reported as having lower absorption and thus more effective for CO2 optics.
Spectral Transmission CVD Zinc Selenide®
BaF2 is an excellent optical material for a broad spectral range in VIS and IR. This enables utilization in sophisticated applications:
● Thermal imaging and night vision with integrated VIS channel
● Optics for astronomical instrumentation
● Infrared laser optics
● Scintillator for the detection of high energy γ-radiation >5Me
