Schematic drawing of the optical set-up at the SST. After reflecting off the dichroic mirror separating the red and blue beams (not shown), the red beam passes the chopper and prefilter. Then a beam splitter sends 10% of the light to the WB camera. The other beam passes the LCs, the high- and low-resolution etalons of the CRISP filter (HRE and LRE resp.), and finally a polarizing beam splitter separating the p- and s-polarized light to the transmitted and reflected beams. All three cameras are 1024  ×  1024 pixel CCD (Sarnoff) cameras running at  ~36 Hz.
