SCHOTT Optical Glass Specifications
SCHOTT optical glasses are specified according to their optical and internal properties. These include: Optical Properties
- Refractive index with tolerances
- Abbe value with tolerances
- Refractive index homogeneity
- Internal transmission
- Color code
- Bubbles and inclusions
- Stress birefringence
Unless specifically requested, SCHOTT optical glass will be delivered in refractive index/Abbe number step 3/3 with a standard test report. The refractive index of all parts of a lot will not deviate by more than ±1 x 10-4
(± 2 x 10-4
for pressing) from the test report.
A detailed description of SCHOTT optical glass properties is available in the 'Optical Glass - Collection Datasheets' that can be found in the Downloads
area. Quality Assurance
SCHOTT is both ISO 9001 and 14001 certified and can be your trusted partner. Our optical glass goes through a stringent quality inspection before delivery. The production of optical glass is continuously monitored at all stages in addition to an elaborate final inspection.
Delivery lots are tested for refractive index scattering, stress birefringence, striae and bubbles according to DIN ISO 10110. A test certificate in accordance with DIN EN 10204 documents the standard supply quality. Upon request, we can also supply test certificates with increased accuracy. For high homogeneous cut blanks, we confirm homogeneity through interferometry.
