Cylindrical Lens – Rectangular Plano Concave (CYLC)
UV Grade CaF2 lenses are designed for use at 193-250nm
- Concave side can be used as a reflector coating substrate
- Anamorphic expansion
Plano-concave cylindrical lenses provide uni-axial negative imaging for anamorphic beam expansion and a wide range of applications. These lenses may also be used as mirror blanks if a concave cylindrical surface mirror is required.
