High resolution in three dimensions with SWIFT and PALM3K

3rd AO4ELT Conference - Adaptive Optics for Extremely Large Telescopes (2013)

F Clarke, N Thatte, M Tecza, K O'Brien, R Houghton, D Tice, L Fletcher, P Irwin, A Verma, R Dekany, R Buruss, J Roberts

SWIFT is a visible light (650-1000nm) integral field spectorgaph fed by the Palomar extreme adaptive optics system PALM3K. With a subaperture spacing of 8cm, PALM3K is capable of delivering diffraction limited performance even in the visible. With SWIFT providing spatially resolved spectroscopy at R=4000, this provides a truly unique facility for high resolution science in three dimensions. We present here some results from the first year of PALM3K+SWIFT science. We also report on our experience of operating a small field of view instrument (1"x0.5") with a high performance AO system, and hope the lessons learned will provide valuable input to designing successful and productive AO plus Instrument combinations for ELTs.


The opto-mechanical design of HARMONI: A first light integral field spectrograph for the E-ELT

HARMONI is a visible and near-IR integral field spectrograph, providing the E-ELT's spectroscopic capability at first light. It obtains simultaneous spectra of 32000 spaxels, at a range of resolving powers from R∼4000 to R∼20000, covering the wavelength range from 0.47 to 2.45 ìm. The 256 ? 128 spaxel field of view has four different plate scales, with the coarsest scale (40 mas) providing a 5? ? 10? FoV, while the finest scale is a factor of 10 finer (4mas). We describe the opto-mechanical design of HARMONI, prior to the start of preliminary design, includi ng the main subsystems - namely the image de-rotator, the scale-changing optics, the splitting and slicing optics, and the spectrographs. We also present the secondary guiding system, the pupil imaging optics, the field and pupil stops, the natural guide star wavefront sensor, and the calibration unit. © 2012 SPIE.


Engineering technology development in the UK for HARMONI: An E-ELT first light instrument

Proceedings of SPIE - The International Society for Optical Engineering 8450 (2012)

F Clarke, A Gallie, D Montgomery, M Tecza, N Thatte

HARMONI is an integral field spectrograph working at visible and near-infrared wavelengths, over a range of spatial scales from ground layer corrected to fully diffraction-limited. The instrument has been chosen to be part of the first-light complement at the European Extremely Large Telescope (E-ELT1). This paper describes the engineering technology development being undertaken at the UKATC and Oxford to support E-ELT HARMONI 2 instrument in its pre-phase-B stage. This includes the description of technology demonstrators for a tracking optical de-rotator to be located within the instrument vacuum vessel, a cryogenic shutter and a compact thermally compensating lens mount system. In addition the material testing facilities available at the UKATC are described which will enable the measurement of material and bolted joint thermal conductivities to 4K and friction/wear properties of material combinations to 20K. This work is undertaken to improve the instrument performance and reduce technical, cost and schedule risk. © 2012 SPIE.


Multiplexing 32,000 spectra onto 8 detectors: The HARMONI field splitting, image slicing and wavelength selecting optics

Proceedings of SPIE - The International Society for Optical Engineering 8450 (2012)

M Tecza, N Thatte, F Clarke, D Freeman, J Komalski

HARMONI, the High Angular Resolution Monolithic Optical & Near-infrared Integral field spectrograph is one of two first-light instruments for the European Extremely Large Telescope. Over a 256x128 pixel field-of-view HARMONI will simultaneously measure approximately 32,000 spectra. Each spectrum is about 4000 spectral pixels long, and covers a selectable part of the 0.47-2.45 μm wavelength range at resolving powers of either R=4000, 10000, or 20000. All 32,000 spectra are imaged onto eight HAWAII4RG detectors using a multiplexing scheme that divides the input field into four sub-fields, each imaged onto one image slicer that in turn re-arranges a single sub-field into two long exit slits feeding one spectrograph each. In total we require eight spectrographs, each with one HAWAII4RG detector. A system of articulated and exchangeable fold-mirrors and VPH gratings allows one to select different spectral resolving powers and wavelength ranges of interest while keeping a fixed geometry between the spectrograph collimator and camera avoiding the need for an articulated grating and camera. In this paper we describe both the field splitting and image slicing optics as well as the optics that will be used to select both spectral resolving power and wavelength range. © 2012 SPIE.
