Cylindrical lenses have curvature in one dimension and are designed for one-dimensional beam shaping. They are typically used to change the shape of a light source in an optical system into a line source. Cylindrical lenses can be used to correct astigmatism in optical systems. They are widely used in high-power lasers, long-distance line interferometers, and other high-precision testing instruments and devices. Cylindrical lenses are also commonly used in optical systems such as synchrotron radiation beamlines, barcode scanners, and high-power laser systems. To meet customer needs, BOXIN offers cylindrical lenses in various materials, including colorless optical glass, laser crystal, fused quartz, radiation-resistant glass, ultraviolet and infrared materials, and metal materials, such as SiO₂, CaF₂, BaF₂, ZnSe, ZnS, etc.

BOXIN has over 100 CNC cylindrical lens milling and polishing machines, as well as more than 40 traditional polishing machines. For precision inspection, we are equipped with ZYGO laser interferometers with various radius diffraction lenses. For measuring generatrix, side sag, and tilt angles, we use cylindrical lens measuring instruments controlled by computer software, which can print data. BOXIN can produce cylindrical lenses in visible light, near-infrared, and far-infrared materials. The processing range is extensive, with lengths from 2mm to 1200mm and widths up to 650mm. Annual production exceeds 2 million pieces.
