◦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.
