HealthyPhoton's TEC cooled MCT Amplified Photodetector is a highly sensitive photovoltaic HgCdTe (mercury cadmium telluride. MCT) detector for sensitive detection of photons in the mid-IR spectral range from 2 to 12 µm.
The detector output can be DC or AC coupled. A multi-stage semiconductor thermoelectric cooler (TEC) is equipped to ensure the active area operating at a temperature ~190K, thereby minimizing the effect of thermal noise. The detector package adopts aluminum alloy materials, which shields the working environment from electromagnetic interference and also effectively dissipates heat.
• Sensitive to mid-IR light from 2 ~ 12 um
• Signal bandwidth: DC/AC ~ 20 MHz
• TEC to hold the temperature at ~190K that greatly reduces thermal noise
• Low-noise, wide-bandwidth pre-amplifier to convert photocurrent into a voltage signal
• Cost-effective
