    Description

    UV Fused Silica Plano-Convex Lenses
    UV fused silica has high transmittance from ultraviolet to near infrared (185-2100nm), and has high transmittance in the deep ultraviolet range. In addition, compared with H-K9L (N-BK7), it has better uniformity and lower thermal expansion coefficient, which is especially suitable for high-power lasers in the ultraviolet to near-infrared range. When converging light, if an absolute magnification of less than 0.2 or greater than 5 is obtained, a plano-convex lens is usually selected. When the magnification is between 0.2 and 5, a biconvex lens is more suitable. In order to reduce spherical aberration, parallel light should be incident on the curved surface of the plano-convex lens during focusing. A variety of coating specifications can be selected.
