MATERIAL - CVD ZnSe (Zinc Selenide) CVD
 |
Crystaltechno Ltd. manufactures spherical plano-convex lenses from ZnSe (Zinc Selenide) CVD material as well as from fused silica, glass and different types of optical crystals.
ZnSe (Zinc Selenide) spherical plano-convex lenses are widely used as focusing transfer optics.
Crystaltechno Ltd. manufactures Zinc Selenide (ZnSe CVD) plano-convex lenses for high power CO2 laser machines. ZnSe CVD plano-convex lenses diameter (25.4 – 50.8) mm is available. AR/AR coating of CVD ZnSe plano-convex lenses both for one wavelength (10.6microns or another) and for the IR spectral range (3 – 12) microns is available.
Perhaps you’ll find the required ZnSe optics at our stock, please see item Optical Crystals.

* Numerical parameters correspond to Lambda = 10.6 microns (n = 2.4).
All prices are FCA Moscow.
Large sizes and another shape of CVD ZnSe lenses are also available according to customer’s requirement.
We produce ZnSe lenses and other ZnSe optics from CVD grown ZnSe laser grade material. Basic characteristics of CVD ZnSe (Zinc Selenide) laser grade material: grain size ( 50-70 ) microns; transparency in spectral range (0.5- 20) microns, index of absorption 0.0005 (1/cm) at 10.6 microns; ZnSe lenses dimensions - (3 – 100) mm, thickness 20mm.
You can see spectral transmittance of ZnSe window (thickness 10 mm).
Because of high refractive index (n = 2.4 at 10.6 microns), Fresnel losses of Zinc Selenide polished surface are equal 17 % (at one side), thus the transmission of Zinc Selenide polished lens equals 68.9% at 10.6 micron. We offer two sides antireflection (AR/AR) coating both for one wavelength (10.6 microns or another) and for the spectral range (3-12) microns. Transmission of AR/AR coated ZnSe CVD lenses - up to 99%.
Crystaltechno Ltd. offers the best ratio of price/quality for ZnSe lenses.
Please contact us for ZnSe lenses pricing of other size, shape and precision requirements.
Perhaps you’ll find the required ZnSe optics at our stock, please see item Optical Crystals.
