One collaboration · distinguishable instrument contexts
EXOhSPEC connects a University of Hertfordshire laboratory test bed with partner instrument development and telescope work in Thailand. This page keeps their hardware, photographs, status and results separate.
Configuration control
The University of Hertfordshire laboratory platform and the Thailand instrument record share programme origins but have different hardware and operating contexts.
University records describe a working test bed intended to support development of a facility instrument. Detailed current laboratory experiments are restricted to approved collaborators.
NARIT describes a compact fibre-fed spectrograph using prisms and a grating and states that a prototype has been installed and tested with the 2.4 m Thai National Telescope. Its observatory equipment listing also describes EXOhSPEC as under construction, so the exact commissioning milestone remains unresolved.
The acquisition and guiding unit holds a star image on the fibre at the telescope. Internal spectrograph control addresses a separate part of the optical system.
The 2019 prototype and proposed final-system requirements describe design intent. Measured performance must be tied to the relevant instrument configuration and method.
Programme optics, fibres, mechanics, software and telescope systems have contributions from the University of Hertfordshire, NARIT and collaborating researchers.
