Optical Glass

Optical glass is a term generally used to refer to a group of glass materials with better optical qualities than standard glass materials like soda lime or borosilicate glass. Optical glass is particularly suitable for use in manufacturing optical components such as precision lenses.

When choosing an optical glass, a number of factors can be considered including density, index of refraction and coefficient of expansion. These should be selected to suit the application requirements so a suitable optical glass can be identified.

Crown glasses, BK7® and B270® glass are all common types of glass typically referred to as optical glass.

Characteristics of optical glass include:

  • High transmission levels
  • Good thermal stability
  • Good chemical stability
  • Cost-effectiveness

Goodfellow Ceramic and Glass Division is able to supply a wide range of ceramic and glass materials as finished components. Our capabilities range from custom-made precision microcomponents with very high tolerance features to large heavy-duty components used in industrial applications. Additionally, standard semi-finished forms such as tubes, rods, bars, plates, crucibles and spheres are often available from our wide inventory. Please contact us with full details of your requirements, including drawings where available, and we will review and respond with a quotation as soon as possible.
