Inorganic Low Index Clad
SH-HT series are formulated for high temperature operations necessary for high power fiber laser applications. Compared to our legendary PC-LAP series which showed severe yellowing, SH-HT series have no color change nor optical transmittance change after 3 hours at 200˚C exposure. The SH-HT series have fluoro-siloxane chemical backbone structure which withstands high temperature continuous operation over 200˚C. The decomposition temperature Td is higher than 350˚C.
