1、 Optical componentsmicrolens arrayThe customized processing projects are as follows

1) Glass non spherical lens



Non spherical lenses can solve the distortion and aberration caused by current spherical lenses, reduce the volume of imaging systems, and improve the overall imaging quality of the system. It has been widely used in important fields such as medical equipment, precision instruments, aerospace, and defense technology, representing the trend of lens development.

Machinable materials include: fused quartz, microcrystalline glass, silicon carbide (ceramic), and polymer materials

Crystal materials (germanium, zinc selenide, magnesium fluoride, etc.)

Caliber: 1000mm

The machining surface accuracy can reach: (P-V) 1/20 λ

The surface roughness of the processed material can reach RMS: 0.3nm




2) Metal reflector



Large aperture metal reflectors can achieve various beam collection, beam collimation, and beam focusing, and are widely used in fields such as astronomical observation optical devices, spectral detection, astronomical telescope systems, sights, beam expanders, infrared systems, concentrated solar energy systems, projection systems, and emission/detection equipment.

At present, the processing of metal mirrors is mainly concentrated within 6 inches (150mm), and our company's aperture reaches 20 inches (500mm), which is at the domestic level.

Machinable materials include: aviation aluminum, copper, steel (nickel plated), alloys

Caliber up to 500mm

The machining surface accuracy can reach: (P-V) 1/4 λ

The surface roughness of the processed material can reach 2nm




3) Singular Optics



Traditional optical processing can only process corresponding surface shapes for flat, spherical, and partially non spherical surfaces. However, the development of singular optics has broken through the bottleneck of optical processing and can achieve high-precision, high-efficiency, and large-sized processing for different optical surface shapes. It is currently the development direction of optical components.

At present, the unique optical components produced by our company have been widely used in scientific instruments, integrated circuits, astronomical telescopes and other fields. The product has the characteristics of large size, high precision, and complex surface shape.
