Ir spectrograph
WebFTIR stands for Fourier transform infrared, the preferred method of infrared spectroscopy. When IR radiation is passed through a sample, some radiation is absorbed by the sample and some passes through (is transmitted). The resulting signal at the detector is a spectrum representing a molecular ‘fingerprint’ of the sample. WebWe present low-resolution optical spectra and classifications of 92 blue objects with mid-infrared excesses in the Large Magellanic Cloud. The majority of these objects were selected with the criteria of U − B < 0 and V < 17 from the potential young stellar object (YSO) candidates in Gruendl & Chu (GC09), which were identified based on Spitzer Infrared Array …

WebJul 1, 1994 · Abstract We have designed an immersion echelle-prism spectrograph for the remote detection of chemicals in the atmosphere. The instrument operates in the 2 and 3 micron atmospheric windows and provides maximum throughput at 0.1 cm-1 resolution. Webwith IR Doppler instruments. At the University of Florida, we are developing a new NIR cryogenic temperature controlled, high resolution, cross-dispersed echelle spectrograph dedicated for high-precision RV measurements. This instrument is called the Florida IR Silicon immersion grating spectromeTeter (FIRST). The primary Figure 2.1.
