Description
General Introduction: Raytek calcium fluoride lens is an excellent material for ultraviolet to near infrared wavelengths (180-8000 nm). Compared with various infrared materials, it has higher average transmittance and lower color difference. In the near-infrared range, its GVD is very low, so it is very suitable for some applications that need to use femtosecond infrared pulse.
Products Name: CaF2 infrared Plano convex lens
Alias: CaF2 infrared Plano convex lens, CaF2 infrared lens, CaF2 Plano convex lens, CaF2 IR Plano convex lens, CaF2 IR ens, CaF2 lens, Calcium fluoride lens, Calcium fluoride Infared lens, Calcium fluoride IR lens,etc
Lens Substrates:
High transmittance CaF2 substrate in infrared band
CaF2 lens is an excellent material for UV to NIR (180-8000 nm). Compared with various infrared materials, it has higher average transmittance and lower color difference. In the near-infrared range, its group velocity dispersion (GVD) is very low, so it is very suitable for the application of femtosecond infrared pulse.

Advantages of uncoated lens
Uncoated lenses are used in optical systems and equipment, mainly because they have a very wide wavelength range, high damage threshold ratio, and do not need to be coated, so they are always cheaper than coated lenses. In addition, the uncoated lens makes the image in the camera look more "retro", which is becoming more and more popular in cinema film production.
