Product Portfolio
  • Infrared Detectors

  • Detectors based on HgCdTe material that offer the highest performance out of all discovered materials suitable for Infrared detection. Our detectors are optimized for MWIR (3-8μm) and LWIR (8-16μm) spectral ranges. It is perfect for creating gas sensors for industry and environmental protection. They are an ideal solution for CRDS, TDLAS or FTIR spectroscopy. Very high parameters of detection and speed of operation make them ideal for applications such as leak detection, transport safety or defense applications. We also offer InAs or InAsSb based detectors that are RoHS compliant and suitable for the consumer market.
      • HgCdTe (MCT) photovoltaic detectors

      • Photovoltaic detectors (photodiodes) are semiconductor structures with one (PV) or multiple (PVM) , homo- or heterojunctions. Absorbed photons produce charge carriers that are collected at the contacts, resulting in external photocurrent. Photodiodes have complex current voltage characteristics. The devices can operate either at flicker-free zero bias or with reverse voltage. Reverse bias voltage is frequently applied to increase responsivity, differential resistance, reduce the shot noise, improve high frequency performance and increase the dynamic range.

                                    There are three models in universal module series:

                                  • Optimized for operation in the spectral range of 3 um to 6.7 um and frequency bandwidth from DC to 1 MHz with photovoltaic detector optically immersed .

                                  • Optimized for operation in the same spectral range and the same frequency bandwidth but with photovoltaic multiple junction detector without immersion microlens.
                                  • The output signal is standard voltage with a fifty Ohms impedance (50Ω). Additional DC output is available as a standard.

                                  • 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.

                                    The internal architecture is similar to standard detection modules. The main difference is that most of the internal functional blocks are configurable.

                                    To provide information about the module status it is equipped with bias and dc offset monitoring circuits. It is possible to build a system with adaptive gain or overload protection. Adjustable bandwidth can help to achieve the best possible noise performance for various signal types.

                                  • UHMS 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 term electronics and mechanics. The system was designed to suport the propagation of high-speed signals, mounting the detector to the enclosure as close ad possible to a PCB board and input circuits. The manufacturing process requires fine tuning of the circuit with a specific detector.

                                    Additionally, it has DC monitor. It is a DC coupled signal, taken directly from the 1st stage preamplifier. One should take into account the 1 VDC offset at the DC monitor output.

                                    This output may be used for:

                                    • measure of the mean optical power by the detector,
                                    • photodetector’s dark current monitoring.

                                    UHSM is the one of the fastest long-wavelength infrared detection modules series on the market.
