Descripción
The Instituto de Astrofisica de Canarias (IAC) is undertaking the design
and construction of a common-user near IR spectrograph (LIRIS) for the
Cassegrain focus of the 4.2 m William Herschel Telescope sited at the
Observatorio del Roque de Los Muchachos. LIRIS will be a near IR
intermediate-resolution spectrograph designed to operate over a spectral
resolution range between 1000 and 5000, with added capabilities for
coronographic, multiproject and polarimetric observations. The
instrument allows the combination of an adequate spatial resolution with
a large useful field of view across the slit, thanks to the use of the
new 1024 X 1024 pixel HgCdTe Hawaii detector manufactured by Rockwell.
All the optics and mechanisms situated inside the cryostat will be
cooled to below 100 K. The detector will operate at 77 K. Calibration
and tracking will be made with the existing Cassegrain A and G Box, into
which a near IR calibration system will be incorporated.
