Optical Glass
More than 120 optical glass types
Here you will be led to an interactive Abbe-Diagram, which gives an overview of all of our optical glass types. Please click on the symbol to the left to get detailed information on properties or downloadable datasheets. For more than 125 years, SCHOTT Advanced Optics has been offering a large portfolio of high-quality optical glasses to meet the needs of a variety of optical and industrial applications, ranging from consumer products to optical systems of research.
We aim to meet future market needs by providing new optical glasses for rapidly-growing innovations and utilizing new melting processes to ensure cost-effectiveness and efficiency. Our range of optical glasses includes:
- Arsenic-free N-glasses
- Glasses suitable for precision molding (low Tg glass)
- Classical glass types with lead oxide as an essential component for outstanding optical properties.
- High transmission glasses ("HT" or "HTultra") with superior transmission.
SCHOTT optical glasses are available in the form of raw glass, cut blanks, pressings as well as finished components.
Our latest list of preferred SCHOTT optical glass includes approximately 120 glass types which are classified into glass groups based upon similar chemical composition and are illustrated in a nd-vd diagram.
You can access an Abbe-Diagram in PDF format as well as an overview of all of our glass types ('Optical Glass - Overview' and 'Optical Glass - Overview (ZEMAX format)')in the downloads area.

SCHOTT Optical Glass Specifications
SCHOTT optical glasses are specified according to their optical and internal properties. These include:
Optical Properties
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.
