Product Description

This plano-convex cylindrical lens features one flat surface and one convex cylindrical surface, providing optical power along a single axis for line focusing and beam shaping. Compared with standard optical glass, calcium fluoride cylindrical lenses deliver lower absorption and improved chromatic aberration control across a broad wavelength range.

 

Performance Advantages

Broadband high transmission from UV to IR

Low refractive index and low dispersion for reduced chromatic aberration

One-dimensional focusing for line optics applications

Excellent infrared performance for mid-IR systems

High-purity CaF₂ single crystal ensures optical uniformity

 

Application Range

Optical and electronic sensor protection

Inspection and measurement equipment

Industrial and scientific optical instruments

Imaging system protective windows

Optical modules, lenses, and prisms assemblies
