Description

The UK Astronomy Technology Centre (UK ATC) is a laboratory within the Science & Technology Facilities Council which is part of UK Research & Innovation. The UK ATC has responsibility within the METIS project to design, build, test and deliver the LMS to our project partners. Within the LMS is a Three Mirror Anastigmat (TMA) which is the subject of this tender. The UK ATC intends to procure it as a “build to print” system with the UK ATC carrying out the design according to manufacturing advice and constraints given by the Supplier.

Total Quantity or Scope

A pre-disperser (a low resolution prism spectrometer) with an exit slit mask is used to define the bandpass within the LM band, acting as an order sorting filter for the echelle. Multiple exposures with rotation of the pre-disperser and main disperser are required to build up a continuous spectrum. The main dispersion optics for the METIS LMS consists of a three mirror system (the TMA) operating in double pass as collimator and camera. An immersed germanium grating is used as the main dispersing element. Performance of the spectrometer will be essentially diffraction limited and with good control of scattered light.
