IR Asphere Lenses

Name: IR Asphere Lenses
Brand: Shenzhen Solar Valley Scitech Development Co., Ltd.

Infrared aspherical lens uses a single point diamond ultra-precision multi-axis free-form surface machining machine, going through ultra-precision single point turning, grinding, measurement, ultra-precision polishing and other processes. Under the condition of precise control of the machine tool and processing environment, the optical aspherical plastic domain ultra-precision machining is achieved. The ultra-high precision correction polishing technology is used to polish the lens surface, and the optical aspherical surface shape accuracy is less than 0.1 micron, and the surface roughness Ra is less than 0.01 micron.
