Optical glass, also known as optical lenses or glass lenses, is typically categorized as plano-convex (PCX), double-convex (DCX), plano-concave (PCV), or double-concave (DCV) lenses. They are commonly made from materials such as soda-lime, borosilicate, and quartz, with diameters varying from 1mm to 300mm and tolerances held to within ±0.1mm. Distinguished by their scratch resistance, these lenses are easy to clean and maintain due to their polished, smooth surfaces that resist oil and chemical contamination. Notably, quartz glass lenses boast a high light transmittance rate of up to 95%. These lenses are essential in various domains including daily life, science, education, and industry, being integral components in lights, cameras, microscopes, telescopes, and collimators, among others.
