The PVI-2TE-4-1×1-TO8-wAl2O3-36 is a state-of-the-art infrared photovoltaic detector designed by VIGO System S.A. This advanced device is engineered with a sophisticated HgCdTe heterostructure, ensuring optimal performance and stability. It operates within the 2.4 – 4.3 µm spectral range and is specifically optimized for peak performance at 4 µm. The detector is equipped with a two-stage thermoelectric cooler, enhancing its efficiency and reliability in various applications.

One of the standout features of the PVI-2TE-4-1×1-TO8-wAl2O3-36 is its integration with a hyperhemispherical GaAs microlens. This design choice significantly boosts the device's performance by improving its optical immersion. Additionally, the detector benefits from a 3° wedged sapphire (wAl2O3) window, which effectively prevents unwanted interference effects, ensuring accurate and reliable measurements.

The device's performance can be further enhanced by applying a reverse bias, which increases response speed and dynamic range. However, users should be aware that while this improves high-frequency performance, it may introduce 1/f noise at lower frequencies. The PVI-2TE-4-1×1-TO8-wAl2O3-36 is housed in a TO8 package and features a compact optical area of 1×1 mm, making it suitable for integration into a variety of systems and applications.
