Plano-Concave (PCV) Cylinder Lenses, 21.0x19.0mm, F=-19.00mm, Uncoated H-K9L Optical Glass, United Optical Technology Co., Ltd (CAT#: STEM-OP-2401-YJL)

Plano-Concave (PCV) Cylinder Lenses, 21.0x19.0mm, F=-19.00mm, Uncoated H-K9L Optical Glass, model 155344, is manufactured by United Optical Technology Co., Ltd.
Cylindrical lenses are used to shape point light sources in one dimension. Typical applications use a single cylindrical lens to convert a collimated laser beam into a line beam. To reduce spherical aberration, when diverging the beam, the concave surface of the lens should face the light source. K9 optical glass is an optical material with excellent wide-spectrum transmission. It has high transmittance from 350nm to 2000nm, has high hardness, and can withstand a variety of physical and chemical stimuli. The content of bubbles and impurities is low, so it is often used as the substrate for various optical components to make various optical components.
