Appendix B
Telescope Instrumentation


The design of the WHT allows great flexibility in instrumentation, as this telescopes allows fast and easy switching between the Cassegrain and Nasmyth foci. For this reason, and to take advantage of the large light collecting power of this telescope, operation and developmental efforts focus here. Also visiting instruments, i.e. instruments built and used by external groups for their own use, are welcome at the WHT and have attracted a great deal of attention. The INT and JKT are equipped with a restricted set of instruments that match the capability of the telescopes whilst satisfying the requirements of a large percentage of users as well as the financial constraints and scientific priorities for these telescopes. A broad functional division in instrumentation capability between the WHT, INT and JKT is as follows:



William Herschel Telescope Spectroscopy and spectropolarimetry over a wide range of resolving powers

Multi-object spectroscopy

Areal spectroscopy

Optical and infrared imaging

High spatial resolution imaging
Isaac Newton Telescope Intermediate-dispersion spectroscopy

CCD imaging
Jacobus Kapteyn Telescope CCD imaging

The following table summarises the common-user instruments which were available during 2002 and 2003.
