Monolithic faceplates developed by SCHOTT are manufactured without using lead additives, thus meeting Restriction of Hazardous Substances (RoHS) standards. Applications for the RFG92 fiber-optic faceplates include digital x-ray sensors that integrate CMOS technology.
The company can manufacture a complete faceplate without needing to assemble it from several smaller faceplates. Such construction becomes an advantage for both processing optical performance and x-ray attenuation, says Jörg Warrelmann, business manager for SCHOTT Lighting and Imaging. In particular, the one-piece design creates more uniform x-ray attenuation across the faceplate. The RFG92 also improves transmission within the visible range while using the same x-ray attenuation as previous comparable devices.
All faceplates are produced according to customer specification. They can be sized up to 320 by 320 mm, although special sizes up to 450 by 450 mm are possible. Moreover, they’re manufactured hermetically for use with x-ray scintillators.
SCHOTT will show the faceplates at the COMPAMED Trade Fair in Dusseldorf, Germany (Nov. 20-22).
