Optical Glass
AOHONG optical glass, also called optical lens, glass lens and optical glass lenses, is always divided into plano-convex (PCX), double-convex (DCX), plano-concave (PCV) and double-concave (DCV) lens.
The materials are always soda-lime, borosilicate and quartz. The diameters range from 1 mm to 300 mm and tolerance is controlled below ±0.1 mm. Our glass lens can resist scratching, which lengthen its service lifetime. Besides it is easy to clean and maintain because the smooth and polishing glass are not easy to contaminated by oil or other chemicals. Apart from that, quartz glass have high light transmittance up to 95%.
Optical lenses are widely used in daily life, science, education and industry, such as lights, camera, microscopes, telescopes, collimators and so on.
