Abstract

ECHARPE spectrograph - Espectrógrafo ECHelle de Alta Resolução para o telescópio Perkin-Elmer - is being designed at LNA - Laboratório Nacional de Astrofísica, Brazil - to be mounted on 1.60 meter telescope at Pico dos Dias Observatory, Brazil. It will offer a spectral resolution of R ~ 50000, in the interval 390-900 nm and in a single exposition. It will be a fiber fed, bench spectrograph with two channels: blue and red, fed by two optical fibers (object, sky or calibration) with aperture of 1.5 or 2.0 arcseconds. This paper reports on technical characteristics of the spectrograph mechanical design and presents a new developed mounting system for echelle grating and collimator and relay mirrors, which allows linear and rotational adjustments in all degrees of freedom without using springs.
