First light: February 1984.
De-commissioned: May 1997.
Designed and built by: RGO
Description: During the first commissioning nights,
photographic plates were used as the default detector. The CCD Camera at the prime focus
of the INT was commissioned from July 1985 to May 1997. When it was
first commissioned two CCD chips were in use: RCA 58612 (thinned and back-illuminated)
and GEC P8600 (front-illuminated). The former has a significantly higher
detective quantum efficiency, especially in the blue, but higher readout
noise. On the other hand, the pixel size of the GEC chip was 22 µm,
compared with 30 µm for the RCA chip (0.54 and 0.74 arc sec, respectively),
so the former gives significantly better sampling in good seeing. The last
CCD detector used was Tektronix, with a pixel size of 24 µm or 0.59
arc sec. It was replaced by the new CCD-mosaic Wide Field Camera.
