B 270®

B 270® is an enduringly popular material thanks to strong technical credentials such as excellent optical performance and high quality geometrical and surface properties. SCHOTT customers also benefit from a unique flexibility in terms of design and thickness, covering a wide variety of requirements.

High transmittance from UV-A to NIR

The consistently strong level of transmittance achieved by B 270® ranges all the way from UV-A up to NIR regardless of glass thickness, with no characteristic loss in the VIS range. Under standardized light D65, the luminous transmittance of B 270® can reach an outstanding 91.9 %.

Homogenous refractive index

Combined by SCHOTT’s state-of-the-art manufacturing process, the top-quality raw materials that make up B 270® enable tightly controlled tolerance levels for the refractive index (with an accuracy of ± 0.001), regardless of glass thickness.

Flexibility of thickness

B 270® is available in a wide range of stock thicknesses to suit a customer’s individual need, from 10 mm down to 0.3 mm. If you require a different thickness, many other sizes can be manufactured on request.

High surface and geometrical quality

SCHOTT’s industry-leading manufacturing techniques ensure that B 270® offers highly impressive geometrical properties. All available thicknesses are produced with a fire-polished surface and homogenous geometry, ensuring consistent performance regardless of application.
