LEST high resolution spectrograph.
Abstract
The authors present a design for a high resolution grating spectrograph for the LEST. It is based on the LEST science requirements and is open to future developments in detector technology. The proposed spectrograph is intended to be standard post focus instrument with a high degree of flexibility and versatility. To this end they propose a dual channel echelle-type instrument which allows to simultaneously record a variety of spectral bands in the visible and near infrared, and with a total wavelength range from 380 to 2800 nm. The instrument includes a scan unit for two-dimensional solar spectroscopy.
