Zinc Selenide Optics
CVD zinc selenide (ZnSe) is a chemically inert material with
high purity, strong environmental adaptability, and ease of
processing. It has low optical transmission loss and excellent
transparency. It has a low absorption coefficient and high
resistance to thermal shock, making it the preferred material
for high-power CO2 laser optical components.

The Application of ZnSe Optics
Due to its uniform and consistent refractive index, this
infrared material is also an ideal material for protecting
windows and optical components in forward looking infrared
(FLIR) thermal imaging systems. At the same time, this material
is also widely used as windows and lenses in medical,
industrial thermal radiometers and infrared spectrometers, JT
offers a wide variety of ZnSe lenses or ZnSe windows.

Â
JT offers lenses, windows, mirrors and other optics that
customized for infrared applications. Infrared optical material
selection depends on customer's requirements, the materials
include germanium, silicon, zinc selenide, zinc sulphide
,sapphire, calcium fluoride, and many more. Our infrared optics
manufacturing capabilities cover the entire infrared spectrum:
near-infrared (NIR 0.7µm to 0.9µm), short-wave infrared (SWIR
0.9µm to 2.3µm), mid-wave infrared (MWIR 3µm to 5µm), and
long-wave infrared (LWIR 8µm to *4µm).
