Positive Meniscus Cylindrical Lens
Positive Meniscus Cylindrical Lenses are precision lenses with one convex and one concave cylindrical surface along the same axis, providing net positive optical power while focusing light to a line along a single axis rather than to a point. Chenyu Optics manufactures positive meniscus cylindrical lenses in BK7, fused silica, optical glass and infrared materials, with custom focal length, dimensions, surface quality and coating according to customer drawings.
Positive Meniscus Cylindrical Lens Overview
Positive Meniscus Cylindrical Lenses are precision lenses with one convex and one concave cylindrical surface along the same axis, providing net positive optical power and focusing light to a line along a single axis rather than to a point.
Compared with a plano convex or double convex cylindrical lens, the meniscus geometry helps correct aberration when combined with other cylindrical or spherical elements in an optical system, while the perpendicular axis remains unaffected, making it suitable for beam shaping and anamorphic imaging assemblies with tighter aberration control requirements.
Chenyu Optics supports custom positive meniscus cylindrical lens manufacturing according to customer drawings, including custom material, focal length, dimensions, surface quality and coating for prototype and repeat production.
Key Advantages of Positive Meniscus Cylindrical Lens
