Applications
Optical glasses are used in a broad range of applications, from consumer goods markets to the more traditional high-tech industrial optics markets:

  • Consumer goods market applications:
  • Binoculars
  • 35mm, APS and digital still cameras and video cameras
  • Interchangeable camera lenses
  • Digital projectors
  • Microscopy
  • Medical engineering
  • Laser fusion
  • Reprographics
  • Professional image processing

Materials
Optical glasses are divided into glass groups, which include glasses with a similar chemical composition and thus also have a similar optical characteristic. SCHOTT Optical Glass Map

Forms of Supply
Fine annealed optical glass with up to five non-machined, as-cast surfaces.
Cut blanks: with standard or with increased optical and internal properties and dimensional tolerance requirements.
Pressings

Specifications
Optical properties:
Refractive index with tolerances
Abbe value with tolerances
Refractive index homogeneity
Internal transmission and color code
Internal properties:
Striae
Bubbles and inclusions
Stress birefringence

Usually it is sufficient to specify only the optical and internal properties.
However, for some applications the chemical, mechanical or thermal properties might also be required.  A detailed description of the properties of each available glass is available to download.
 
Quality Assurance

Optical glass is subjected to stringent quality inspection before delivery. All stages of the optical glass production are continuously monitored. Additionally, an elaborate final inspection is performed.
A test certificate in accordance with DIN EN 10204 documents the standard supply quality. Delivery lots are tested for refractive index scattering, stress birefringence, striae and bubbles according to DIN ISO 10110. On request we can also supply test certificates with increased accuracy.
For high homogeneous cut blanks we confirm homogeneity by interferometry.
