Null test optics for the MMT and Magellan 6.5-rn f/1.25 primary mirrors
The instruments used to interferometrically measure the optical surfaces of the 6.5-rn f/i .25 prirnaiy rnirrors for the MMT conversion and Magellan Telescopes rnust compensate over 800 un surface departure frorn the best fitting sphere. The errors in the optical test rnust not contribute rnore than 0.04 arc seconds FWHM to the final image and the conic constant rnust be held to 0.01%. This pap...
متن کاملMitigation of H2RG persistence with image illumination
Residual charge generation, or image persistence, in infrared detectors is a problem that affects many low-light astronomical instruments. The HAWAII-2RG in the MMT & Magellan Infrared Spectrograph shows significant persistence when first powered up. We describe here how we reduce the persistence sensitivity of this detector by exposure to light.
متن کاملPhotometric Calibrations for the Sirtf Infrared Spectrograph
The SIRTF InfraRed Spectrograph (IRS) is faced with many of the same calibration challenges that were experienced in the ISO SWS calibration program, owing to similar wavelength coverage and overlapping spectral resolutions of the two instruments. Although the IRS is up to ∼300 times more sensitive and without moving parts, imposing unique calibration challenges on their own, an overlap in phot...
متن کاملGMTNIRS – The High Resolution Near-IR Spectrograph for the Giant Magellan Telescope
We present a conceptual design for a powerful, high-resolution near-infrared spectrograph for the Giant Magellan Telescope (GMT). This instrument, the Giant Magellan Telescope Near-Infrared Spectrograph (GMTNIRS), uses silicon immersion gratings as the primary dispersing elements. The design has two modules, one for 1.1-2.4 m for use under native seeing conditions and one for 3-5.5 m to be used...
متن کاملEngineering performance of IRIS2 infrared imaging camera and spectrograph
IRIS2, the infrared imager and spectrograph for the Cassegrain focus of the Anglo Australian Telescope, has been in service since October 2001. IRIS2 incorporated many novel features, including multiple cryogenic multislit masks, a dual chambered vacuum vessel (the smaller chamber used to reduce thermal cycle time required to change sets of multislit masks), encoded cryogenic wheel drives with ...
