N-BK7 plano-convex cylindrical lenses are manufactured from fine annealed glass and polished to tight tolerances to meet the demanding requirements of applications including line illumination for metrology, laser scanning, spectroscopy and diode laser beam shaping. Plano convex cylindrical lenses could be offered with AR coated at different wavelengths. We offer custom made service for the lenses, just send us drawings or specifications.
