InGaAs Amplified Photodetector with Thermoelectric Cooler
-
Thorlabs' PDA10DT(-EC) Amplified Detector is a thermoelectrically cooled, photoconductive, extended-range InGaAs (indium gallium arsenide) detector. It is sensitive to light in the mid-IR spectral range from 0.9 to 2.57 µm. Two rotary switches control the gain amplifier and detector package bandwidth, allowing performance to be optimized for a variety of applications.
The gain switch features eight discrete steps from 0 - 70 dB, while the bandwidth switch provides eight discrete steps from 500 Hz - 1 MHz. The thermoelectric cooler (TEC) uses a thermistor feedback loop to hold the temperature of the detector element at -10 °C, minimizing thermal contributions to the output signal. For best results, we recommend connecting the BNC output cable (not included) to a 50 Ω termination.
