Zinc Sulfide Rectangular Windows

Zinc Sulfide Windows（rectangular）

Zinc sulfide rectangular windows are used as protective windows for electronic sensors or external environmental detectors. The shape is rectangular, used to separate the inside and outside of the instrument, protecting the internal components. The characteristics are low absorption, low scattering, and hardness and impact resistance. It can have high transmittance in both visible light and infrared, making it an ideal choice for systems with visible light and medium or long wave infrared sensors. UM OPTICS can provide different types of window sheets such as circular, rectangular, wedge-shaped, perforated, and stepped sheets.
