The **PVA-2TE series** represents a cutting-edge line of two-stage thermoelectrically cooled infrared photovoltaic detectors, meticulously engineered by VIGO System S.A. These detectors are crafted using advanced InAs1-xSbx alloys, ensuring high performance without the inclusion of mercury or cadmium, thus adhering to the stringent RoHS Directive. A distinctive feature of these detectors is the 3° wedged sapphire (wAl2O3) window, which is specifically designed to prevent unwanted interference effects, enhancing the overall reliability and accuracy of the measurements.

These detectors are optimized for a spectral range of **2.0 to 5.5 µm**, making them ideal for a variety of infrared detection applications. The PVA-2TE series is available in two variants, each with unique characteristics tailored to specific needs. The PVA-2TE-3 variant features an epitaxial InAs heterostructure with a peak wavelength of 2.9 µm, while the PVA-2TE-5 variant utilizes an epitaxial InAsSb heterostructure with a peak wavelength of 4.7 µm. Both variants are housed in a robust TO8 package, ensuring durability and ease of integration into existing systems.

The detectors are equipped with a two-stage thermoelectric cooler, maintaining an active element temperature of approximately 230 K. This cooling mechanism is crucial for achieving high detectivity and responsivity, with the PVA-2TE-3 variant boasting a detectivity of ≥5.0×10¹⁰ cm·Hz¹/²/W and the PVA-2TE-5 variant achieving ≥4.0×10⁹ cm·Hz¹/²/W. These specifications underscore the series' capability to deliver precise and reliable performance in demanding environments. The PVA-2TE series is an exemplary choice for professionals seeking advanced infrared detection solutions that combine innovation, compliance, and superior functionality.
