20x30mm Schott N-BK7 Uncoated Plano-Concave Cylindrical Lenses
CPG offers both uncoated and UV-coated plano-concave cylindrical lenses. The UV-coated lenses have an antireflection coating for the 245 - 400 nm range on both surfaces that the light goes through. UV-grade fused silica offers high transmission in the deep UV and exhibits virtually no laser-induced fluorescence (as measured at 193 nm), making it an ideal choice for applications from the UV to the near IR. These negative cylindrical lenses can be used to expand light but only in one dimension, which makes them useful for one dimensional shaping of light sources. A typical application is to use a single cylindrical lens to turn a collimated laser into a line generator. Pairs of cylindrical lenses may be used to anamorphically shape images. To minimize the introduction of aberration, the curved surface of the lens should face the source when used to diverge a beam.
