Descripción
New dispersive elements providing relative high resolution (R=2200) have
been recently incorporated in the near infrared spectrograph LIRIS.
These elements are founded on a rather novel design based on a
diffractive pattern engraved in fused silica, which is placed between
two prisms. These new components are pushing forward the scientific
capabilities of the instrument by enhancing the medium resolution
spectroscopic mode of operation. Details on the design, specifications
and measured performances, as well as aspects related to the integration
and astronomical tests in the instrument are presented.
