Cylindrical Plano-concave Lens (BK7) 20×30mm −150mm Focal Length 633 - 1064nm

CLB-2030-150NIR1

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 BK7 for from visible range to infrared wavelength range.
◦BK7 lenses are also available with three types of anti-reflection coatings, visible wavelength range, in the near-infrared range and in the infrared range.
◦Cylindrical lenses are often used in an optical system to change the shape and aspect ratio of the illumination light beam.
