Edmund Optics Inc. has released TechSpec aspheric lenses of UV fused silica, which can be used for designing biophotonics systems and medical devices. Having low f numbers, the lenses provide a clear aperture of 90% and are manufactured to a 60-40 surface quality with a surface accuracy as low as 0.75 μm rms and a diameter tolerance of ±0.1 mm. Available with a 25-mm diameter at focal lengths of 25 and 30 mm, the lenses have a low coefficient of thermal expansion and a high operating temperature. They are computer-optimized to eliminate spherical aberration and to minimize higher-order aberrations.
