Applications of B 270®
As one of our most popular products, B 270® has been relied upon for decades by our customers for a wide variety of applications, from standard optical components to packaging solutions for consumer electronics. A true all-rounder, B 270® continues to provide versatility and reliability in a vast number of areas.
Night vision systems
Night vision technologies – including image intensifiers and active infrared (IR) systems – require protective cover glasses that combine high optical transmission with mechanical durability. SCHOTT B 270® offers excellent transmission of up to 92 % at 2 mm thickness across the 400–1100 nm spectral range, enabling clear, high-contrast imaging even in challenging environments such as total darkness, fog, or smoke. Its outstanding scratch and impact resistance, along with proven weatherability, makes it an ideal choice for use in security surveillance, defense optics, and advanced driver-assistance systems (ADAS).
Optical filters
Optical technology never stands still, but despite the many advances in this field, applications such as high-end digital cameras rely on the finest quality optical filters to protect sensors and other sensitive components. The homogenous transmittance achieved by B 270® makes it an ideal substrate for a variety of filter coatings, closely controlling the light for the best possible performance.
Digital projection
Advanced optical systems such as digital projectors are only as good as their component materials. These must offer stable optical properties in terms of transmittance, dispersion and refractive index in order to guide the light with efficiency and precision through the optical path. The high performance of B 270® matches the demands of several optical systems, and due to its flexibility in thickness, offers a number of cost advantages in processing.
Life sciences and biotech
Modern diagnostics applications such as microfluidics rely on materials with high optical properties and low intrinsic autofluorescence to achieve the high analytical accuracy demanded by the life science and biotech fields. B 270® meets these requirements and provides an outstandingly smooth, fire-polished surface for coatings, resulting in easier, more cost-effective processing.
Reference samples
High-performance coatings for substrate materials are manufactured with stringent quality requirements. In order to meet the specifications of particular applications, reference samples are required for each batch of these coating processes. The homogenous transmittance properties of B 270® allow customers to measure the pure performance of their coatings in an accurate and reliable, user-friendly way.
