As optical systems are pushed to be better, faster, and cheaper, it becomes necessary to explore aspheric solutions. Aspheric surfaces can increase the numerical aperture of a lens while minimizing system aberrations. Additionally, when designed into a lens system, aspheres may enable a reduction of lens elements, which can reduce weight, increase throughput, and simplify mechanical tolerancing and assembly. TECHSPEC® Precision Aspheric Lenses offer the benefits of an aspheric element combined with the manufacturing precision of state-of-the-art grinding and polishing equipment.With the available prescription data, these lenses can be easily designed and integrated into complex optical systems. Featuring low f/#s for optimum light gathering and focusing performance, these lenses are computer optimized to eliminate spherical and minimize higher order aberrations. VIS coating option provides <1.5% reflection from 425-675nm, whereas NIR coating provides <1.5% reflection from 600-1050nm.
