Request Info

Techspec ultraviolet (UV) fused-silica precision aspheric lenses combine the benefits of an aspheric element with the precision of sophisticated grinding and polishing equipment. They feature low f-numbers for optimum light gathering and focusing performance and a variety of coating options, making them suitable for collecting and focusing low-intensity UV sources including fluorescent dyes, fluorophores and mercury light sources.

The lenses are computer optimized to eliminate spherical aberration and minimize higher-order aberrations. The UV fused silica substrate offers a low coefficient of thermal expansion and a high operating temperature, ideal for tightly toleranced applications in the visible and infrared. The lenses provide a clear aperture of 90 percent 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 +0.0/-0.1 mm.

The lenses are currently available with a 25-mm diameter at focal lengths of 25 and 30 mm. Additional diameters, focal lengths and coating options are scheduled to be released in early 2008.

Gregg Fales, product line manager, said, “Edmund Optics’ precision aspheres have been integrated into countless applications in the semiconductor, photonics and defense industries. The introduction of our UV precision aspheres will provide similar design flexibility to system designers in the biophotonics and medical industries.”

Techspec UV precision aspheric lenses are RoHS compliant.
