SCHOTT B270 is an ultra-white modified sodium calcium glass with high transparency, which is widely used in the optical field. It is favored for its excellent optical properties and excellent processing characteristics. B270 has a transmittance of up to 92% in the visible range, which can be increased to more than 99% when treated with an anti-reflective coating, ensuring a clear field of view in a variety of optical applications. The glass has a uniform refractive index and minimal variation, making it suitable for use in precision optical systems. In addition, the thermal expansion coefficient of B270 is 9.4 × 10⁻⁶ K⁻¹, showing good thermal stability, and can maintain stable performance in the environment with large temperature changes. It also has excellent anti-ultraviolet ability, which can effectively resist the influence of solar radiation. Easy to process and suitable for mass production, the B270 is widely used in lenses, filters, displays and other optical components. Its high surface quality and geometric size make it ideal for a variety of high-precision optical applications.
