Thin film coating unit


IBS : Ion Beam Supttering machine

We have a sputtering optical coater and various instruments for measurement and inspection of thin film devices used in Gravitational wave detector and other astronomical instruments. Designs and fabricated various thin film coating. Its products include flight IR-rejection filter for Hinode satellite, ultra-long focal-length mirror and high reflective mirror (99.97 % at 1064 nm) for gravitational wave detector. And we are studying various problems in design and fabrication of optical devices.
