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
