ZnSe Cylindrical Plano-Convex Lenses
MATERIAL - ZnSe (Zinc Selenide) CVD
 |
Crystaltechno Ltd. manufactures cylindrical lenses from CVD ZnSe (Zinc Selenide) material as well as from fused silica, glass and different types of optical crystals.
CVD ZnSe (Zinc Selenide) cylindrical plano-convex lenses are widely used as focusing transfer optics for infrared IR applications including CO2 laser optics.
We offer ZnSe plano-convex cylindrical lenses with round and rectangular design (according to customer's specification).
AR/AR coating of CVD ZnSe plano-convex cylindrical lenses both for one wavelength (10.6 microns or another) and for the infrared IR spectral range (3-12) microns is available.
Perhaps you will find the required Zinc Selenide (CVD ZnSe) lenses and other ZnSe optics ZnSe optics at our stock, please see item Optical Crystals.

* Numerical parameters correspond to Lambda=10.6 microns (n=2.4).
We produce ZnSe cylindrical lenses from CVD grown ZnSe laser grade material. Basic characteristics of CVD ZnSe (Zinc Selenide) laser grade material: grain size (50 - 70) microns; index of absorption 0.0005 (1/cm) at 10.6 microns, transparency in spectral range ( 0.5- 20) microns,
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%.
You can see spectral transmittance of ZnSe window (thickness 10 mm).
Please contact us for ZnSe cylindrical lenses pricing.
Perhaps you will find required ZnSe (Zinc Selenide) lenses and other Zinc Selenide optics at our stock, please see item Optical Crystals.
