Optical glass ultra-precision aspheric lens, CNC polishing ultra-precision aspheric lens
Ultra-precision molded aspherical lenses are manufactured with tungsten steel molds. Our molded aspherical lenses have very high precision and can be coated or uncoated.
We have our own capability of mold development, and we are very good at developing molded aspherical lenses.

Map Optical offers non-coated and coated anti-reflection lenses with aspheric surfaces.
Antireflection membrane options include IR1, NIR2.
Zinc selenide based sheets are suitable for infrared applications.
Aspheric lens can well correct spherical aberration and chromatic aberration, and it is often used in barcode scanning, laser collimation, optical imaging and other fields.
Aspheric lenses are designed with a single element, which helps to minimize the number of lenses in multi-lens optical fittings.
