INOUIRY
UV fused silica offers high transmittance in the deep UV and virtually no laser-induced fluorescence (measured at 193 nm), making it ideal for applications from the UV to the near-infrared.
This series of negative cylindrical lenses offers excellent unidirectional beam expansion, making them useful for shaping light in one dimension along the light source. A typical application is converting a collimated laser beam into a line beam using a single cylindrical lens. Using a pair of cylindrical lenses can also achieve distorted beam shaping. To minimize spherical aberration, the curved surface of the lens should be oriented toward the light source when diverging the beam.
