| NAME |
The Visible Infrared Thermal Imaging Spectrometer (VIRTIS) for the Rosetta Orbiter
|
| TYPE |
|
| DESCRIPTION |
The VIRTIS instrument provided two capabilities: high-resolution visible and infrared imaging in the 0.25 to 5 micron range at moderate resolution, via the VIRTIS-M channel; and high-resolution spectroscopy in the 2 to 5 micron range via the VIRTIS-H channel. The two channel could operate simultaneously to observe the same area in a combined mode. VIRTIS-M was a combination of a Shafer telescope and an Offner imaging spectrometer with two focal plane arrays - one in covering 0.25-1 micron (called VIS), one covering 1-5 micron (called IR). VIRTIS-H was a cross-dispersed spectrometer using a prism and a grating, resulting in a spectrum dispersed in 9 orders across a focal plane detector array.
