The 80020 InGaAs Detector exhibits excellent stability and sensitivity over its spectral responsivity range. This model is a low noise detector that operates at room temperature; no TE cooling or liquid nitrogen is needed. The detector has a built-in trans impedance amplifier that is powered from Oriel’s 80351 FT-IR scanner. The amplifier allows gain selections to be made from 104 V/A to 109 V/A. It also offers three selectable time constant settings, allowing the detector to operate at the lowest possible bandwidth setting for the experiment in order to minimize noise levels. The 80020 includes an aspheric focusing lens with X-Y adjustment and a standard Oriel 1.5-Inch Series female flange.
