Plano Concave Lens – IR Grade CaF2 (PCC)
Calcium Fluoride Lenses- Ideal for wavelengths over 2000 nm
- Focusing or imaging applications
- Focal Length: f = -R / (n-1)
- n: refractive index
- R: radius curvature
These plano-concave lenses are made from infra-red grade Calcium Fluoride and are excellent for use with lasers emitting in the 2 – 5 micron range. They are supplied uncoated but anti-reflection coatings are available on request. Please contact the Lambda’s sales team for more coating information.
