Optical Glass

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.

Advantages:

Chemical Stability and Easy Maintenance: The glass material’s anti-corrosion
properties make it easy to clean and maintain.
Precise Tolerance: With over a decade of experience in optical glass
manufacturing, we can tailor tolerances to meet your needs, even achieving
minimal values for high-precision applications.
Surface Covering: Our surface coverings assist in anti-reflection and
filtering.

Applications:

Magnifi , cation: Convex lenses serve as magnifying glasses, aiding in the
observation of minuscule objects.
Education: Optical lenses play a significant role in physics and are widely
used in schools for educational purposes.
Instrumentation: Medical, biological, and astronomical instruments such as
microscopes, telescopes, and collimators frequently employ optical lenses.
Photography: Glass lenses are integral to the imaging process in cameras.
Lighting: Optical glass aids in light manipulation, concentrating or scattering
rays for specific purposes.
