Spectrogon AB´s filters on the Rosetta spacecraft.

Spectrogon AB (Täby, Sweden) is proud to have developed and manufactured the optical filters in the Rosetta spacecraft´s OSIRIS imaging system. The Rosetta spacecraft, orbiting comet 67P/Churyumov-Gerasimenko takes images through Spectrogon AB´s UV, VIS and NIR filters with 12 filters in the NAC and 14 filters in the WAC cameras on board.

Rosetta’s OSIRIS camera instrument
The Optical, Spectroscopic, and Infrared Remote Imaging System (OSIRIS) is the main imaging system of the Rosetta spacecraft. Consisting of two cameras, the narrow-angle camera (NAC) is intended for high-resolution mapping of the nucleus, while the wide-angle camera (WAC) is optimized for mapping the gas and dust in space in the proximity of the comet.
