Cylindrical Plano-concave Lens (Synthetic Fused Silica) 20×50mm −100mm Focal Length

CLSQ-2050-100N

Skip to the beginning of the images gallery

Cylindrical plano concave lens has a concave curvature in the vertical direction and has no curvature in the horizontal direction. When used in combination with a plano-convex cylindrical lens an elliptical shaped beam can be sharped into a circular beam for use in semiconductor and other laser applications.

Details

◦Plano Concave Cylindrical lenses are available in highstrength synthetic fused silica which has high laser damage threshold used in applications with 350nm ultraviolet light.
◦Cylindrical lenses are often used in an optical system to change the shape and aspect ratio of the illumination light beam.

Remark	-
Attention	The cylindrical plano-concave lens has chromatic aberration, the focal length will vary depending on the wavelength. Please check the “wavelength characteristic of the focal length data” on “Technical Data” for the focal lengths of each wavelength. When using a plano-concave cylindrical lens parallel light should incident to the concave side first. There is a possibility that the spherical aberration will increase and optical performance of the system will be degraded if use in reverse. Transmissions losses due to reflection off the front and rear surfaces of the lens can be minimized by coating the surfaces. Consult our Sales Division for anti-reflection coatings suitable for your application.
