Cylindrical Lenses
► Material from DUV to IR
► Custom dimension and shapes
► Diameter from 2 to 500 mm
► Clear aperture: Central 90% of diameter
► Irregularity : λ/10@632.8nm
► Surface quality: 10-5 S/D
► Centration: ＜1′
► Standard and custom coating options available
► High laser damage threshold
Cylindrical lenses condense or expand light in only one single dimension. CASTECH offers Plano-Convex Cylindrical Lenses, Plano-Concave Cylindrical Lenses and Achromatic Cylindrical Lenses, which are made of Optical glass, Fused Silica, BK7, CaF2 or ZnSe with uncoated or coated options and cover from ultraviolet(UV) to infrared(IR) spectral region. Utilizing a range of processing technologies including tradition polishing, high speed polishing or ion beam figure(IBF) and best-in-class metrology, CASTECH has the ability to ensure consistent high-quality performance of each lens.
MetrologyComputer Generated-Hologram (CGH) is commonly utilized as null for testing cylindrical optics. CASTECH equips with cylinder CGH which creates cylindrical wavefront to test a specific cylindrical surface. Each cylinder CGH is able to measure a family of cylindrical surfaces of similar F/# but different sizes.
