Imager Specifications
- SBIG Research STL-11000M (made by the Santa Barbara Instruments Group)
- 4008x2762 pixels (Med. Res.: 2004x1381, Low Res.:1336x920)
- 9 micron pixels => 0.280"/pixel
- 37.25x25.70mm detector surface => 18.7'x12.6' coverage
- 16 bits/pixel => dynamic range of 65 536
- 21 Mb image files with no binning
- Anti-Blooming Gate
- ~60 000 e- Full Well Capacity (ABG)
- Dark Current: 1.5 e- / pixel / s
- Read Noise: 11 e-
- Exposures of 0.01 to 3600 seconds (0.01 s resolution)
- Gain: 0.8 e- / ADU
- Cooling: Thermoelectric, -30 C from ambient minimum
The imager has four standard resolution modes: no binning,
2x2 binning, 3x3 binning, and 9x9 binning. It can also be used in Nx1,
Nx2, and Nx3 binning modes where N is an integer between 1 and 256. This
is very useful when using the Spectrograph.
Spectral Response
The ST-11000M camera uses a Kodak KAI-11000M CCD. It has a spectral
sensitivity range of
340 nm to 730 nm (>20%), peaking at 500 nm. See Fig. 1.

Note that this CCD is somewhat less sensitive than our ST-8E (up to 20%
lower in QE betwen 400-700 nm, although the difference increases to 50%
above
750 nm) but the FOV is far larger (a factor 3).
