WebAn ATR accessory operates by measuring the changes that occur in an internally reflected IR beam when the beam comes into contact with a sample. An IR beam is directed onto an optically dense crystal with a high refractive index at a certain angle. This internal reflectance creates an evanescent wave that extends beyond the surface of the ... WebMany FT-IR detectors operate at room temperature while others require cooling, with liquid nitrogen (77 K) for example. Thermo electric cooling (TE or Peltier cooling) provides enhanced, 100% line stability for the DLaTGS detector, minimizing response changes due to changes in room temperature. For indium gallium arsenide (InGaAs) detectors ...
