B270i Discs for Superior Optical Quality and Precision

B270I Discs

B270I discs are made from a high transmission optical glass known for its excellent uniformity and clarity. Often used in imaging systems, analytical instruments and photonic devices, B270l discs offer high light transmissions and minimal distortion, making it ideal for precision optical applications. They are chemically stable and resistant to staining, adding to their suitability for both lab and industrial environments.

We offer a wide range of standard sizes and in the event these do not suit your application we can manufacture to your custom requirements
