The new ROSS2 optical camera


The new optical camera, ROSS2, is a simultaneous multi-channel imaging camera delivering four different bands onto four quadrants of the same 2kx2k CCD detector, covering from 400 to 950 nm, split by plate dichroics.

The new camera is under integration in Merate optical labs, for preliminary acceptance tests, and it will be mounted onto REM telescope in Q1 2012.

Here some characteristics:

(*) assuming: newly coated telescope mirrors, seeing = 1 arcsec, dark current <1 e-/min, RON <4e-, rebin = 2X, sky brightness = 21

CCD parameters:

The response of the g', r', i', z' filters is reported below.
