Optical Glass

Customized Glass Lens for Camera and Lights
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%.

Many pieces of optical lenses in different sizes are on the ground.
OG-01: We can produce various sizes of concave and convex optical glass lenses for different applications.
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.
There are two lights with glass lens covers.
OG-03: The glass lens are used in lights to scatter or concentrate the beam of light.There is a set of microscope on the table.
OG-04: Convex lens is used as magnifying glass in microscope.
There is a set of equipment to test the convex lens imaging principle.
OG-05: Optical glass is a important part in physic and it is used in laboratory for education purpose.Many sizes of camera lenses are on the ground.
OG-06: Camera lens is a essential part of camera.
