Kaleido Technology, a leading supplier of precision-molded glass optics and ultra-precision machined components, now offers molded cylinder lenses with aspheric profiles in a wide range of glasses. Applications include slow-axis collimation for diode lasers, bar-code scanners and others.

Technical director Dr. Palle Geltzer Dinesen says: “Traditional manufacturing of cylinder lenses with aspheric profiles is associated with very high costs that prohibits their use in many applications. By deploying our free-form ultra-precision machining capabilities for tooling and our cost-effective precision-molding technology, we have driven the cost of these lenses down; opening for a much wider usage of aspheric cylinder lenses with their enhanced performance as compared to traditional spherical cylinder lenses”.

Currently Kaleido offers aspheric cylinder lenses with a local radius of curvature from 1.5 mm and upwards. Lens dimensions up to 30 mm square. Materials include a wide range of precision-molding glasses from all of the major suppliers.
