EKSMA Optics Cylindrical Lenses

These lenses are used in laser scanners, spectroscopy, dye lasers, acousto-optics, optical processors and other similar applications. They are the best for circularization of diode laser outputs. Earlier remarks made about plano-convex and plano-concave spherical lenses, with regard to aberrations and conjugate ratios, are also applicable to cylindrical lenses.
A variety of anti-reflection coatings is available for these lenses. For appropriate coating please refer to the COATINGS section. We can supply custom cutting, edging, coating or complete fabrication if required.
