The TECHSPEC Near UV achromatic lenses provide transmission in the 345 to 700 nanometer (nm) range. They are designed to minimize the spot size for polychromatic illumination in the 345 to 550 nm region, and work with fluorescence applications. The lenses provide greater than 90% transmission from 360 to 700 nm and supply greater than 50% transmission at 334 nm with no spherical aberration or coma. They are available in 12.5 millimeter diameter models in 25-, 30-, 40-, 50- and 60-millimeter effective focal length (EFL) and in 25 millimeter diameter models in 50-, 60-, 75-, 100- and 125-millimeter EFL. All models include a UV-VIS coating.
