LAFAYETTE, Colo., July 30, 2015 — Rocky Mountain Instrument Co. has expanded its custom lens product line with a new generation of cylindrical lenses. Designed for deep-ultraviolet and far-infrared applications, the lenses focus incoming light in one dimension. They are used in applications where a point image needs to be transformed into a line image or when the height of an image needs to change without causing a change in width. The lenses are available in a variety of sizes, shapes and materials and are designed per customer specification. Optical materials include fused silica, BK7, high-index glass, CaF2, MgF2, BaF2, ZnSe, Si, Ge and sapphire. Sizes range from 10 mm to 6 in., depending on focal length and thickness.
