Infra-red and Sub-mm Instrumentation
The research activity of the Optical Science Laboratory in the far infrared spectral region is dedicated to the design, modelling and characterisation of optical systems and components for astronomical instruments. These have substantially different requirements to optical instruments. Although the mechanical design tolerances are not as tight due to the larger wavelengths, infrared optics require a complete thermo-mechanical characterisation due to the very low temperature at which they need to operate (below 4K). We are involved in the calibration and characterisation of the most recently deployed infrared satellite instrumentation (Planck-HFI and Herschel-SPIRE instruments).
research includes the design and characterisation of optical
components for polarised radiation modulation, the characterisation
of real optical elements (and the anomalies they introduce) in the
presence of polarised radiation, instrument design for the next
generation of satellite spectrometers and novel imaging systems for
long wavelengths. This work is carried out in collaboration with
other UK and European research groups notably the STFC-Rutherford
Appleton Laboratory and Cardiff University".
