The KPA25 Precision Aspheric Lens is an uncoated aspheric lens, made with L-BAL35 optical glass, with 50.0 mm diameter and 37.5 mm effective focal length. 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.

KPA25精密非球面透镜是由L-BAL35光学玻璃制成的无涂层非球面透镜,直径50.0 mm,有效焦距37.5 mm。非球面透镜可以减少透镜元件的数量,从而减少光学组件的尺寸和重量。非球面可以在减小系统像差的同时增加透镜的数值孔径。这些精密非球面透镜经过计算机优化,具有最佳的性能和最小的像差。通过在任何标准光学设计软件中输入透镜参数,可以计算出精确的性能参数
