Plano-Convex Cylindrical Lenses (CLB-P / CLSQ-P)
Model：CLB-P；CLSQ-P
Overview
Plano-convex cylindrical lenses (CLB-P/CLSQ-P): curvature in the vertical direction only, used to focus laser light into a thin line or change the aspect ratio of illumination. Available in BK7 (VIS-NIR, three AR coating options) and synthetic fused silica (high LIDT below 350 nm), focal lengths 15-1000 mm, sizes 10x10 to 30x100 mm, ideal for line focusing, fluid measurement and beam shaping.Description
Overview
Plano-convex cylindrical lenses have curvature in the vertical direction and none in the horizontal direction. They focus laser light into a thin line for experiments and fluid measurement, and change the aspect ratio of illumination in optical systems.
Features
- Two materials: BK7 (CLB, VIS-NIR) and synthetic fused silica (CLSQ, high LIDT for UV below 350 nm)
- BK7 lenses available with VIS / NIR / IR AR coatings (PM / PIR1 / PIR2)
- Focal lengths 15-1000 mm, sizes 10x10 to 30x100 mm
- Custom sizes and focal lengths available; custom AR coatings on uncoated lenses
- Compatible mounts: CHA-25 / CHA-60 / CHA-130
Applications
- Line focusing of laser beams
- Fluid measurement with wide line beams
- Beam shaping and aspect-ratio control
