Anew imaging instrument for Spectr-UF Space mission

The Field Camera Unit (FCU) is one of the main scientific instruments of the Spektr-UV space mission. The main task of the BCP is to obtain images of astronomical objects in several spectral ranges. For this purpose , three channels are provided in the design of the FCU: vacuum ultraviolet (VUV) channel (115-176 nm) with high spatial resolution, equipped with an MCP receiver with a CsI photocathode; near ultraviolet (NUV) channel (150-320 nm) with high spatial resolution, equipped with an MCP receiver with a GaN photocathode; near ultraviolet and optical band channel (UVO) (180-1000 nm) with a 4.5 x 4.5 arc min field of view and CMOS receiver. The MCP receivers of the VUV and NUV channels are sun-blind (sensitivity in the optical range is 3-8 orders of magnitude less than in the ultraviolet). In addition to the mode of obtaining images using light filters, a low-resolution field spectroscopy mode is provided.In addition, the optical scheme allows to implement the coronograph mode according to the scheme Lio and polarimeter mode. If there is a request from the scientific community, the list of filters and the parameters can be modified.
