Frequently Asked Questions
Aspherical lenses are designed to reduce or eliminate spherical aberrations compared to spherical lenses.
Aspherical lenses offer improved optical quality, reduced optical elements, and lower design costs. They also result in a lighter and more compact optical system with higher transmittance.
Aspherical lenses can be fabricated using a wide range of materials including copper, aluminum, optical glass, ZnSe, ZnS, CaF2, Ge, Si, GaAs, and chalcogenide glass types.
These lenses can be processed with calibers up to 350mm.
These lenses are fabricated using a state-of-the-art single point diamond turning (SPDT) machine, ensuring ultra-high precision shape and contouring with Ra<3nm and PV<0.2um.
