Double Convex Cylindrical Lens
Double Convex Cylindrical Lenses are precision lenses with two cylindrically curved convex surfaces along the same axis, focusing light to a line along a single axis rather than to a point, with optical power distributed across both surfaces. Chenyu Optics manufactures double convex cylindrical lenses in BK7, fused silica, optical glass and infrared materials, with custom focal length, dimensions, surface quality and coating according to customer drawings.
Double Convex Cylindrical Lens Overview
Double Convex Cylindrical Lenses are precision lenses with two cylindrically curved convex surfaces along the same axis, focusing light to a line along a single axis rather than to a point.
Compared with a plano convex cylindrical lens, distributing optical power across both surfaces allows a shorter focal length for a given radius and aperture, while the perpendicular axis remains unaffected, making it suitable for beam shaping, line generation and anamorphic imaging applications with more compact focal length requirements.
Chenyu Optics supports custom double convex cylindrical lens manufacturing according to customer drawings, including custom material, focal length, dimensions, surface quality and coating for prototype and repeat production.
