Optical Glass

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.

Features and advantages

Stable chemical property and easy to clean

Glass material have the advantages of anti-corrosion and easy to clean and maintain.

Tight tolerance

We are specialized in manufacturing optical glass for more than 10 years and we can control the tolerance according to your requirements. In some precision application, we can minimize the tolerance into very tiny figure.

Surface covering

Surface covering can help in anti-reflection and filtering.

Application

Used as magnifying glass

The convex lenses are used as magnifying glass to help people to observe tiny thing.

Educational application

Optical lens is a important part in physic, they are widely used in school for education purpose.

Used in instruments

Optical lenses are widely used in medical, biology and astronomical instruments, such as microscopes, telescopes, collimators and so on.

Used in camera

In camera, the glass lenses are used for imaging.

Used in lights

Optical glass are helpful to concentrate or scatter the ray of light to achieve special purpose.
