The Design
and Development of NIRSPEC: A Near-Infrared Echelle Spectrograph for the
Keck II Telescope
by Ian S. McLean et al. SPIE vol. 3354 pp. 566-578
Abstract
The design and development of NIRSPEC, a near-infrared echelle spectrograph
for the Keck II 10-meter telescope is described. This instrument
is a large, facility-class vacuum-cryogenic spectrometer with a resolving
power of R = 25,000 for a 0.4" slit. It employs diamond-machined
metal optics and state-of-the-art infrared array detectors for high throughput,
together with powerful user-friendly software for ease of use.
