Cylindrical Plano-convex Lens (BK7) 20×20mm 25mm Focal Length Uncoated
CLB-2020-25P
Cylindrical plano convex lens has a convex curvature in the vertical direction and has no curvature in the horizontal direction. They are often used to condense a laser beam into a thin line.
◦Plano Convex 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.
