Zinc SelenidePrecision optical compoments
Zinc Selenide lenses are an excellent choice of materials for IR lenses for application between 600 nm to 16 microns wavelengths. Its low absorption coefficient makes it a perfect candidate for applications/instruments using C02 lasers. In mid IR regime it has a very low GVD which makes it suitable for applications using femtosecond IR pulses.
