Calcium fluoride (CaF2) Spherical Lenses

Calcium fluoride, as an important material widely used in the field of optics, is highly favored for its high transmittance in the range of 350 nanometers to 7 micrometers. Whether in spectral windows or lenses, calcium fluoride demonstrates its outstanding performance. Additionally, it is a common choice for thermal imaging systems cooled at low temperatures.

Outstanding Performance, Wide Applications

Calcium fluoride’s characteristics of low absorption and high damage threshold make it the preferred material for optical components in excimer laser systems. Its low refractive index allows for application in optical systems without the need for additional antireflection coatings, providing greater flexibility for optical designers. The Knoop hardness of calcium fluoride lenses reaches 158.3, ensuring durability and stability in various environments.

Various Shapes to Meet Different Needs

Our calcium fluoride lenses offer a variety of shape options, including spherical planoconcave, planoconvex, concaveconvex, or aspherical, to meet the design requirements of different optical systems. Whether it’s for focusing systems, laser components, or optical sensors, calcium fluoride lenses are up to the task.
