Cylindrical Plano-concave Lens (Synthetic Fused Silica) 20×40mm −30mm Focal Length
CLSQ-2040-30N
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.
