BOSHI optical compound eyes lens, the high-precision Optical Compound Eyes Lens (also named optical fly eye lens), a core custom optical component developed and manufactured by Shanghai Silk Optical Technology Co., Ltd., an affiliate of Jiangxi Boshi Intelligence Technology Co., Ltd. (BOSHI), a professional Chinese optical manufacturer with advanced full-process optical processing capabilities. The company is equipped with state-of-the-art high-precision processing and testing equipment, including imported Sumitomo production facilities, and holds ISO9001 quality certification. All optical products are manufactured and assembled in dust-free workshops, with strict full-process quality inspection by professional QC teams to guarantee ultra-high optical precision and stable performance. As a key category of injection-molded plastic aspheric optical lenses, the optical compound eyes lens is included in the company’s comprehensive product portfolio, which also covers VR/TOF lenses, aspheric laser collimating lenses, beam combining lenses, TIR lenses, HUD backlight module lenses, LED street lenses, as well as free-form surface and aspheric optical parts. The company supports both standard mass production and fully customized design & processing for non-standard optical products. This compound eyes lens is widely applied in infrared rangefinders, laser radar systems, and optical transmitting & receiving instruments. The matched aspheric lenses enable critical functions including laser alignment, focusing, and fiber coupling, as well as Gaussian beam shaping (collimation, focusing, homogenization) for optical measurement, laser medical treatment, and laser processing. The aspheric design also delivers superior imaging clarity and resolution, while supporting the miniaturization of optical systems.
