Product Description

General

We can mass-produce various high-precision optical components, including spherical, flat, prism, cylindrical, and aspherical elements, covering a range from visible light to infrared wavelengths. The materials used include standard optical materials, infrared materials, silicon carbide, and various optical crystals. For infrared materials, processing is equipped with ultra-precision single-point diamond turning lathes, capable of machining materials like germanium, silicon, and sulfide with a maximum diameter of φ440mm. The company offers complete solutions for the CNC processing, inspection, and manufacturing of optical aspheres in the visible light range, with capabilities to produce secondary, higher-order, coaxial, and off-axis aspherical optical parts with diameters up to φ800mm. Additionally, it can design and manufacture various large aspheric primary and secondary mirror systems with different technical specifications, achieving surface shape accuracy at an industry-leading level.
