CaF₂ crystal Optical crystal materials High transmittance

CaF₂ crystals have a wide optical transmission range (good light transmission performance in the wavelength range of 0.13μm~10μm), low stress birefringence (no obvious intrinsic birefringence above 200 nm), which is a material for making various optical window prisms and lenses.

Main advantages

• High hardness and corrosion resistance
• High optical transmittance and low scattering rate
• Good mechanical and chemical stability

Main application fields

• Optical Lens: Optical instrument manufacturing, laser technology application, optical material manufacturing,etc.
• Laser resonator mirror: Laser manufacturing, laser application, etc.
• Optical coating material: Optical component manufacturing, optical coating services and other industries
• The protective window of infrared sensor: Infrared sensor manufacturing, infrared thermal imager manufacturing, etc.
