WebZinc Selenide (ZnSe) is a relatively soft material that scratches easily and it is not recommended in harsh environments because its Knoop Hardness is only 120. ISP Optics Zinc Selenide (ZnSe) Windows are particularly useful for 10.6µm CO2 laser applications, due to its low absorption.

WebThe results were fitted with the standard formula: n2=A + [Bλ2/ (λ2−c2)] where n is the refractive index and λ is the wavelength in microns. For ZnSe the best values of the parameters are A=4.00, B=1.90, and c2=0.113; for ZnTe, A=4.27, B=3.01, and c2=0.142; and for CdTe, A=5.68, B=1.53, and c2=0.366. WebAlthough germanium has a very good internal transmittance and thermal conductivity, it is not suitable for a wide range temperature application due to its fairly large temperature dependent refractive index. Figure 1 & 2 show the refractive index and its temperature dependent coefficient as a function of wavelength for selected temperatures.
WebZnSe also transmits some visible light, unlike germanium and silicon, thereby allowing for visual optical alignment. However, it is quite soft and will scratch easily. ZnSe has an index of refraction of 2.403 at 10.6 µm. When handling optics, one should always wear gloves.
