Znse Optical window
- Low Dispersion
- Available Uncoated or AR Coated
- Ideal for Thermal Imaging, FLIR, and Medical Systems
ZnSe Optical Windows are high-quality infrared (IR) transmission components made from zinc selenide material. They offer excellent transparency from 0.6 to 16 µm, making them ideal for CO2 laser systems, thermal imaging, and infrared spectroscopy. With low absorption and high resistance to thermal shock, ZnSe windows ensure reliable performance in demanding optical applications. Custom sizes and coatings are available to meet specific requirements.
