5x0.2 mm CaF2 Optical Window, AR Coated

Product description

Calcium fluoride (CaF2) high-precision windows are designed for thermal imaging applications, providing excellent transmission across a wide wavelength range from 180 nm to 8 μm. These windows, available in both uncoated and anti-reflective (AR) coated options, are ideal for use with excimer lasers and in cryogenically cooled systems. Their low absorption coefficient and high damage threshold make them suitable for demanding environments. Custom sizes and prototypes can be sourced to meet specific application requirements.
