Negative Meniscus Cylindrical Lens
Negative Meniscus Cylindrical Lenses are precision optical components featuring a curved meniscus profile and cylindrical optical power, designed to provide negative focal length and control beam divergence along a single axis. Compared with conventional negative cylindrical lenses, the meniscus design provides improved aberration control and optimized beam shaping performance. Chenyu Optics manufactures negative meniscus cylindrical lenses in BK7, fused silica and UV fused silica, uncoated or with UV AR, VIS AR and NIR AR coatings.
Negative Meniscus Cylindrical Lens Overview
Negative Meniscus Cylindrical Lenses are precision optical components featuring a curved meniscus profile and cylindrical optical power, designed to provide negative focal length and control beam divergence along a single axis.
Compared with conventional negative cylindrical lenses, the meniscus design provides improved aberration control and optimized beam shaping performance. These lenses are widely used in laser beam shaping, beam expansion, optical scanning, line generation and machine vision systems.
Chenyu Optics supports custom negative meniscus cylindrical lens manufacturing according to customer drawings, including custom diameter, focal length, cylindrical radius and coating design for prototype and repeat production.
