High multiplex and precision: the design and development of FLEX, a grid-based fiber positioner with large patrol radius and minimized telecentric error
Aaron Omadutt, Roelof S. de Jong, Will Saunders +5
In next-generation spectroscopic facilities, high-multiplex fiber positioning systems must operate within highly constrained focal surfaces, such as the Wide-Field Spectroscopic Te…
Athermal package for OH suppression filters in astronomy part 1: design
Carlos Enrique Rordriguez Alvarez, Aashia Rahman, Hakan Ãnel +3
We present the design of an athermal package for fiber Bragg grating (FBG)filters fabricated at our Institute for use in ground-based near-infrared (NIR) telescopes. Aperiodic mult…
ANDES, the high resolution spectrograph for the ELT: science goals, project overview and future developments
A. Marconi, M. Abreu, V. Adibekyan +286
The first generation of ELT instruments includes an optical-infrared high-resolution spectrograph, indicated as ELT-HIRES and recently christened ANDES (ArmazoNes high Dispersion E…
ANDES, the high-resolution spectrograph for the ELT: RIZ Spectrograph preliminary design
Bruno Chazelas, Yevgeniy Ivanisenko, Audrey Lanotte +44
We present here the preliminary design of the RIZ module, one of the visible spectrographs of the ANDES instrument 1. It is a fiber-fed high-resolution, high-stability spectrograph…
