TL;DR
The paper presents the design of RISTRETTO, a high-resolution spectrograph with seven spaxels fed by single mode fibers, aimed at detecting reflected light from nearby exoplanets, emphasizing stability and precise order spacing.
Contribution
It introduces a novel seven spaxel single mode spectrograph design with a stable, vacuum, and thermally controlled environment for exoplanet detection.
Findings
Design achieves precise order spacing on detector
Instrument stability through vacuum and thermal control
Feasibility of using single mode fibers for high-resolution spectroscopy
Abstract
The RISTRETTO project is aiming to build an instrument that will detect the reflected light from close-by exoplanet. It is a two stage instrument: An extreme AO system in the visible, followed by a seven spaxel single mode High resolution Spectrograph. In this paper we present the design of this spectrograph: a classical echelle spectrograph fed with single mode fibers. Standard single mode fibers have been chosen and are forming a long tilted slit in order to have the right order spacing on the detector. The instrument will be under vacuum and thermally controlled in order to make it stable.
