Product Introduction

Standard CVD polycrystalline zinc selenide, non-multispectral grade without hot isostatic pressing (Non-HIP). It features high transmittance only within 8–12μm long-wave infrared band, widely used for thermal imaging equipment. It delivers uniform refractive index and low absorption loss in LWIR range. AR anti-reflection coating is optional upon request.

We fully support custom fabrication: circular / rectangular windows, wedges, flat prisms and large-size raw blanks. OEM & ODM orders are accepted. All sizes have no export license restrictions. It is a classic infrared optical substrate for thermal cameras, infrared thermometers and laboratory optical test instruments.
