This webpage is an addition to a physical poster presented at Astronomdagarna 2017 in Kiruna. Here you will find the PDF version of the poster, as well as a selection of useful links and additional information and content related to the CRIRES+ spectropolarimeter.
◈ The "+" for CRIRES: enabling better science at infrared wavelength and high spectral resolution at the ESO VLT ADS
◈ Characterizing the cross dispersion reflection gratings of CRIRES+ ADS
◈ Wavelength calibration from 1-5μm for the CRIRES+ high-resolution spectrograph at the VLT ADS
◈ Novel infrared polarimeter for the ESO CRIRES+ instrument ADS
◈ Opto-mechanical design of a new cross dispersion unit for the CRIRES+ high resolution spectrograph for the VLT ADS
◈ Concept and optical design of the cross-disperser module for CRIRES+ ADS
◈ CRIRES+: a cross-dispersed high-resolution infrared spectrograph for the ESO VLT ADS
◈ CRIRES+: Exploring the Cold Universe at High Spectral Resolution ADS
This photo shows the core part of the polarimeter, which is a beam-splitter. Beam-splitters split the light
from a source into different beams with different polarisation status. Here, the beam-splitter (optimised to work in the infrared) splits
the light from a smartphone torchlight. August 2017
Installing the CRIRES+ spectropolarimetry unit at ESO headquarters. July 2017
The spectropolarimetry unit is installed in the warm optics enclosure. This enclosure also contains calibration devices, and will
be placed between the telescope and the CRIRES+ cryostat. July 2017
Mechanical drawing showing the top-view of the spectropolarimeter. July 2017
The CRIRES cryostat. This enclosure is cooled to cryogenic temperatures, and contains most optical parts,
the main échelle grating as well as cross-dispersing gratings, and the science detectors among others.
This cryostat, together with the warm-optics enclosure, and the electronic cabinets, will be placed on the
Nasmyth platform of the VLT UT3.
