Aspheric lenses can be used to reduce the number of lens element, thus reduce the size and weight of optical assemblies. Aspheric surfaces can increase the numerical aperture of a lens while minimizing system aberrations. These precision aspheric lenses are computer optimized for optimal performance with minimum aberrations. Exact performance parameters can be calculated by feeding the lens parameters in any standard optical design software. AR.10 coating option provides <1.5% reflection from 250-450 nm, AR.14 coating option provides <1.5% reflection from 425-675 nm, and AR.16 coating provides <1.5% reflection from 600-1050 nm. UV Fused Silica Precision Aspheric Lenses features low f-numbers for optimum light collection with excellent transmission in the UV spectral range. With low coefficient of thermal expansion, UV Fused Silica aspheric lenses can be used in application where insensitivity to change of temperature is required.
