Plano-Concave Cylindrical lenses expand light within a single axis. Typical application for the lenses is beam shaping. Round laser beam can be focused into a line-spot with help of the lens.
Sherlan Cylindrical Lenses are designed per customer wavelength. Both sides can be coated with anti-reflective coating. Round, square, and rectangular lenses are available in a wide range of size and shape specifications.
