Bühler K.K. Product Lineup

HELIOS is a sputtering device developed for the production of high-quality optical films. It is particularly suitable for the manufacture of multilayer filters that require low absorption and low dispersion. The HELIOS series is available in two types: 400 and 800 (substrate sizes).

Rivolt Optics, with nearly 160 years of history as the world's largest vacuum equipment manufacturer, has extensive experience as an industry leader and provides vacuum thin film manufacturing equipment and processes to achieve high-precision optical coatings. We offer a variety of vacuum chamber sizes, from research and development applications to large-scale mass production, to meet the diverse needs of our customers. Starting in 2018, we will globally deploy the IBF system, which performs ultra-precision optical lens surface polishing in a vacuum using ion beams. 【Features】 - Ion beam processing of various substrate materials used in precision optics enables ultra-precision polishing to λ/200! - Can be used for the production of laser optical components, astronomical telescopes, DUV, EUV, X-ray mirrors, and more. - Polishing treatment of substrate surfaces is conducted using ion beams within a high vacuum chamber. - Precision processing of large flat plates and lens surfaces (spherical and aspherical) is achieved with 6-axis control. *English version of the materials is available. Please feel free to contact us for more details.
