Product Description
The plano concave cylindrical lens, with one flat and one concave cylindrical surface, only affects light propagation in one direction. It can expand parallel or divergent light into a linear virtual image, offering better directional control than spherical lenses in laser shaping and line optics. Available materials like Schott, Hoya, Ohara, CDGM optical glass, Crystal, and Corning fused silica, along with optional multilayer anti-reflection coatings, meet diverse wavelength and environmental needs while improving transmission efficiency. Manufactured via precision polishing, it has stable negative focal length control, improved beam uniformity, and strict tolerances on surface accuracy, centration, and surface quality, ensuring long-term reliability in laser scanning and spectroscopic applications.
