Cylindrical Plano-concave Lens (Synthetic Fused Silica) 30×40mm −80mm Focal Length

CLSQ-3040-80N

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.
◦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.

Guide
  • Lenses are available in a large selection and in custom sizes and focal lengths.
  • In addition to our standard coating we offer custom anti-reflective coating at specific wavelengths.
  • We offer holders to mount our catalog cylindrical lenses, consult our Sales Division for assistance in your selection (CHA).
  • WEB Reference Catalog Code/W4022
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.
