Product Case Studies

Calcium fluoride (CaF2) is a commonly used material for manufacturing non spherical lenses. It has high hardness and low refractive index, which can produce thinner lenses.

Calcium fluoride non spherical lenses have high stability and corrosion resistance, making them suitable for use in high temperature and harsh environments. It has good thermal stability and can withstand high operating temperatures, and is commonly used in infrared optical systems.

The surface shape of calcium fluoride non spherical lenses can be elliptical or curved, depending on the requirements of the applied optical system. Its manufacturing technology is relatively complex, usually using techniques such as laser cutting, grinding, or polishing

Calcium fluoride non spherical lenses are widely used in fields that require high-precision and high-performance optical systems due to their excellent optical performance and flexible design, including:

• High end photography and videography: In professional cameras and camcorders, it is used to improve imaging quality, reduce color difference and aberration.
• astronomical observation: Used in astronomical telescopes to obtain clear interstellar imaging.
• laser technology: In laser systems, used for precise focusing or shaping of laser beams.
• Scientific research and medical equipment: Used in microscopes, spectrometers, and other precision instruments to improve the accuracy of observation and measurement.
