Irregular cylindrical lens
Irregular cylindrical lens
Special-shaped cylindrical lenses are the core competitive product of Benchu Optoelectronics. On the basis of standard cylindrical optical processing, Benchu Optoelectronics adopts self-equipped precision engraving machines (8 units) and CNC machining centers (3 units) to carry out complex special processing including crystal orientation cutting and positioning, drilling, grooving, edge cutting and square pocketing for cylindrical lenses, enabling full freedom in lens shape design — rectangular, polygonal, L-shaped, holed, grooved and other customer custom profiles can all be fabricated according to drawings. Special-shaped cylindrical lenses are widely used in integrated optical systems requiring precise matching between optical components and mechanical structures, and serve as key components for highly integrated products such as precision instruments, laser modules and medical optical devices. Benchu Optoelectronics has the mass production capacity for small and medium batches of special-shaped cylindrical lenses. The sampling cycle is negotiable depending on complexity, usually 7 working days.
