ZnSe Aspheric Lens, 25.4 mm Dia, 20.0 mm EFL, 0.64 NA, 1.0 mm thick
The ZNPA11 Zinc Selenide IR Aspheric Lens is a 25.4 mm in diameter with effective focal length of 20.0 mm aspheric lens. Zinc Selenide has wide variety of usage in high power CO2 laser systems because of its low absorption coefficient and high resistance to thermal shock. ZnSe aspheric lenses provide diffraction limited focusing performance, making it ideal for focusing the output of a CO2 laser. It is an excellent choice for any IR applications due to its broad wavelength range (0.6 µm to 16 µm).
