TECHSPEC® Precision Aspheric Fused Silica Lenses are specially manufactured with benefits of an aspheric element combined with precise manufacturing process that includes state-of-the-art grinding and polishing equipment. The fused silica optics cab be easily designed and integrated into complex optical systems. The optics feature low f/#s for optimum light gathering, focusing performance and low coefficient of thermal expansion. The computer optimized fused silica lenses eliminates spherical and minimize higher order aberrations. UV fused silica optics substrate offers low coefficient of thermal expansion.
