It has a broad spectral response, close to that of DTGS, but lets you measure signals ~100X weaker. It also acquires data about 8X faster than DTGS. The 80026 comes with an industry standard, 8 hour dewar. It has a two stage, low noise amplifier. The first stage has three settings: LOW (gain of 10), MED (gain of 30), and HIGH (gain of 100). The second stage provides AC coupling and 10X amplification. • High sensitivity • Broad spectral response, 5,000 to 600 cm-1 1000 2000 3000 4000 5000 6000 7000 8000 WAVENUMBER (cm-1) NORMALIZED SIGNAL 1.0 0.9 0.8 0.7 0.6 0.5 0.4 0.3 0.2 0.1 0 5.0 2.5 1.66 1.25 WAVELENGTH (ìm) Specifications Responsivity Range 5,000 - 600 cm-1 (2 - 17 ìm) Detector Element Size 1 x 1 mm Window Material ZnSe Preferred Beam Splitter KBr Typical D* (Peak) 5 x 1010 Operating Bandwidth (with amplifier) 100 Hz to 40 kHz Ordering Information Model Description 80026 Liquid N2 Cooled MCT Detector See our website WEBfor more info Fig. 1 Spectrum of 1273K blackbody captured with the 80026 MCT Detector, KBr beamsplitter and the MIR 8025™ Scanner.
