Imaging with LDSS-2

LDSS-2 is described in more detail in Section . Although primarily a spectroscopic instrument it can be used for deep broad-band imaging, and its imaging mode is often used to select targets for deep spectroscopic observations. A broad-band BVR filter set is provided, and because of the large number of air-glass surfaces in LDSS, and the fact that the anti-reflection coatings are optimised over the range 370-750 nm, LDSS is not recommended for imaging observations outside this range.

• Filters. A set of BVR ``Harris'' filters is provided to fit in the LDSS filter wheel, which is in the collimated beam. No other filters are large enough to accomodate the entire collimated beam.
• CCD detector. The available detectors are summarised in Table .
