S p e c t r o s c o p y I n s t r u m e n t s 1287 Email: [email protected] • Web: newport.com MONOCHROMATORS AND SPECTROGRAPHS SINGLE CHANNEL DETECTION SYSTEMS MINISPECTROMETERS BENCHTOP SPECTROMETERS AND CCD CAMERAS FT-IR SPECTROMETERS ACCESSORIES FOR SPECTROSCOPY INSTRUMENTS Silicon and InGaAs Detectors for Oriel MIR8025TM FT Spectrometers This family of photodiode detectors covers the near infrared region, 14,000 to 6,000 cm-1 (0.7 to 1ìm). We offer Si and various models of InGaAs detectors. The 80019 Silicon Detector has excellent stability and sensitivity, albeit over a limited range. The InGaAs detectors have a slightly broader spectral response, particularly the 80014 extended InGaAs model, but they are a bit noisier than silicon. These are the preferred detectors for Overtone Spectroscopy. The 80014 Detector requires the 77055 TE Cooler Controller. • Si and InGaAs models • Room temperature and TE cooled WAVELENGTH (ìm) 80014 EXTENDED InGaAs H20 80020 InGaAs 80019 Si WAVENUMBER (cm-1) NORMALIZED INTENSITY 2000 1.0 0.8 0.6 0.4 0.2 0 4000 6000 8000 10000 12000 14000 5.0 2.5 1.66 1.25 1.0 0.833 0.714 Specifications 80019 Silicon Detector 80020 InGaAs Detector 80014 Extended InGaAs Detector Responsivity Range 14,000 - 10,000 cm-1 (0.7 - 1 ìm) 10,000 - 6,000 cm-1 (1 - 1.7 ìm) 8,000 - 4,000 cm-1 (1.2 - 2.5 ìm) Detector Element Size1 mm diameter 1 mm diameter 1 mm diameter Window Material BK7 BK7 BK7 Preferred Beam Splitter CaF2 CaF2 CaF2 Typical D* (cm Hz1/2 W-1) 1 x 1014 1 x 1012 1 x 1012 Operating Bandwidth (with amplifier) 100 Hz to 40 kHz* 100 Hz to 40 kHz* 100 Hz to 40 kHz* Transimpedance gain (A/V) Selectable from 104 to 107 Selectable from 104 to 107 Selectable from 104 to 107 * Gain Dependent Ordering Information Detectors Model Detector Type 80019 Silicon $992 80020 InGaAs $1,678 80014 Extended InGaAs* $3,304 * Requires 77055 TE Cooler Controller TE Cooler Controller Description Model TE Cooler Controller* 77055 * Specify mains voltage when ordering See our website WEBfor more info 80019 Silicon Detector.
