Edmund Optics' (EO; Barrington, NJ) TECHSPEC near-UV achromatic lenses provide transmission in the 345-700 nm range, minimizing spot size for polychromatic illumination in the 345-550 nm region. 

Edmund Optics' (EO; Barrington, NJ) TECHSPEC near-UV achromatic lenses provide transmission in the 345-700 nm range, minimizing spot size for polychromatic illumination in the 345-550 nm region. Ideal for use in simple focusing of common UV light sources in fluorescence applications, including mercury arc lamps, UV LEDs and Tripled Nd: YAG lasers, the lenses feature a simple cemented design and offer an alternative to air-spaced doublets and triplets in the UV region. The lenses provide greater than 90% transmission from 360-700 nm and greater than 50% transmission at 334 nm with no spherical aberration or coma. To accommodate a wide variety of integration options, the lenses are available in 12.5-mm diameter models in 25-, 30-, 40-, 50- and 60-mm EFL and in 25-mm diameter models in 50-, 60-, 75-, 100- and 125-mm EFL. All models include a UV-VIS coating.
