Infrared detection module integrates infrared photodetector, signal processing electronics, optics, heat dissipation systems and other components in common package.
The integration makes detectors less vulnerable to over-bias, electrostatic discharges, electromagnetic interferences and other environmental exposures. Additional advantages of integration are improved high-frequency (HF) performance, output signal standardization, miniaturization, and cost reduction. VIGO offers detection modules with an infrared detector optimized for uncooled or at temperatures acheivable with Peltier-cooler operation in the spectral range from 2 µm to 12 μm.
Various circuit designs have been developed to optimize the performance of the modules in various applications.

IR radiation emitted by an object is concentrated on the active area of an IR detector, generating photoelectric signals which are sensed by the front-end electronics (FEE).

The front-end electronics circuitry is typically used to:

  • Provide optimum conditions for the operation of IR detectors (to achieve high sensitivity, fast response, and a wide dynamic range. This is typically achieved with optimized constant voltage bias and current mode of the photoelectric signal readout.)
  • Protect detector elements against overbias.
  • Amplify the signal within the required frequency band. This could be done with a minimized contribution of the preamplifier  noise to the resulting noise of the detection module.

In addition to front-end electronics, detection modules may include additional electronic blocks for signal conditioning, such as gain blocks, filters, thermoelectric cooler controllers, analog-digital converters (ADC) and other components.

LabM Series

Programmable detection modules enable control of many parameters, such as bandwidth and gain, even during normal operation. This opens up completely new possibilities to designers of measuring systems. In a fully analogue input circuit, many switching elements are used, even with a variable, digitally-controlled capacitance to compensate the transimpedance input stage.

UHSM Series

Many applications require high-time resolution or, equivalently, high frequency-bandwidth optical detection. For these applications, VIGO developed ultra-high-speed detection modules series. It was necessary to apply a special design, both in terms of electronics and mechanics. The system was designed to support the propagation of high-speed signals, mounting of the detector to the enclosure being as close as possible to a PCB board and input circuits. The manufacturing process requires fine tuning of the circuit with a specific detector.
