2. MTCC-01 overview The MTCC-01 (Miniature Thermoelectric Cooler Controller) is the module designed for supplying the thermoelectric cooler (being a part of the cooled IR detector) and providing the temperature stabilization process. The MTCC-01 is suited to work with 2- and 3- stage cooled detector (2TE, 3TE). Due to the compact size, MTCC-01 is especially convenient to use in OEM applications. Features Compact size Low cost Easily configurable by the user High stability and precision Adjustable temperature Low power consumption 2.1.

2.2. TE cooled detector temperature stabilization general information Every cooled detector, besides containing IR sensitive structure, is equipped with: TEC (ThermoElectric Cooler), Thermistor, Depending on the requirements, like responsivity, noise level, and therefore the final temperature, detectors fabricated by VIGO contain 2-, 3- or 4-staged TE cooler. The lowest achievable temperature depends also on ambi ent temperature and the heat dissipated by the detector due to the detector biasing. Considering all the factors and preparing measurements under conditions comparable with those in final application, detectors are described and the final temperature is defined. The thermistor being inside the detector package gives the feedback about the IR sensor temperature and allows the controller to perform the temperature control process. The thermistor is a component common for every type of the IR sensors, which makes the temperature measurement simple and repetitive for each detector. Having the detector parameters measured, the MTCC-01 controller parameters (ma current, depending on the cooler) and final temperature are set, and the system is ready to work. The MTCC-01 module contains low noise and precise analog path, PID controller block, and the power stage for Peltier element driving. It also has diode indicating the actual state of the controller (getting the temperature down / ready to work). Temperature controller basing on the PID algorithm allows the system to quickly achieve the final temperature, keeping it long term stable with small fluctuations and can also adapt to varying environment conditions. The MTCC-01 is a linear controller, so it doesn't introduce disturbances to the IR detection system and does not affect its performance. 5
2.3. MTCC-01 operation Selecting the MTCC-01 parameters Before turning the IR detecting system on, the MTCC-01 controller has to be configured. TEC type (2- or 3stage) and the final temperature is set by shifting the jumpers to the proper positions. Some jumper positions activate the on board potentiometer and allow the user to adjust the final temperature precisely. Potentiometer for temperature adjustment Configuration jumpers UNIT Function 1 2 3 4 2-stage TEC, ITEC MAX = 1.2 A 3-stage TEC, ITEC MAX = 0.45 A Ma. TEC current, no temperature control TDET = 230 K TDET = 220 K TDET = 240 K TDET = 220 to 240 K, adjustable TDET = 240 to 250 K, adjustable TDET = 232 to 245 K, adjustable TDET = 245 to 255 K, adjustable 6
LED indicators MTCC-01 controller has two LED diodes indicating the state of the module. RED diode (marked as POWER) is shining if the controller supply (VSUP) is properly connected. GREEN diode (marked as LOCK) is shining if the detector temperature achieves the set value. After turning on the power supply the GREEN LED is off by maimum 300 seconds depending on the detector type. 2.4. Connectors The picture below shows the pin configuration of the module.

3. Getting started regards complete IR detection kit 3.1. Unpacking Before unpacking, verify if there are no visible damages of the package. Report them to the manufacturer or the distributor. 3.2. Installation & connections Mount the IR module in the measurement setup, Connect all elements with cables provided in the package, Make sure that all the elements are properly connected. 3.3. Switching on procedure Do not switch on the IR module power supply until ALL elements of the IR detection kit are correctly connected with the proper cables, Switch on the thermoelectric cooler controller and wait until detector operating temperature is reached and stabilized. Ready state will be indicated by the LOCK green LED light, Before starting the measurements make sure the load resistance is valid. IR detector module output should be terminated by 50Ω or 1MΩ resistance depending on the bandwidth and is given in the test data provided on the module, Do not manipulate any connectors on the active IR kit this may introduce additional noises to the system or can cause severe damages due to electrostatic discharges. 9
4. MTCC-01 other related information 4.1. CE statement of conformity VIGO System declares that IR detection kit is fully compliant with: EU Low Voltage Directives: 73/23/EEC, 93/68/EEC EU Electromagnetic Compatibility Directives: 89/336/EEC, 91/263/EEC, 92/31/EEC, 93/68/EEC 4.2. Electromagnetic interference To avoid the electromagnetic interferences (EMI), please do not put any electromagnetic source close to the IR module. That may cause interference to the input of the preamplifier and disturb the useful signal in the IR track 4.3. Operating temperature Detector parameters are guaranteed for the environment temperature not eceeding 35 OC. 4.4. Storage information To ensure reliable operation and long lifetime of detector, the following conditions should be fulfilled: Storage temperature: -10ºC + 50ºC and 10% to 90% humidity, Avoid eposing to direct sunlight and strong UV/VIS light as this may result in degradation of a detector performance, Avoid electrostatic discharges (ESD). 10
5. Safety instructions To ensure safe and failure-free operation of the MTCC-01 controller, comply with the following precautions: Before connecting the power supply to the mains, make sure if it is compatible with the mains voltage and fre quency. Do not use the controller if the temperature and the air humidity etends the values valid for the MTCC-01 controller. Use the proper cables to connect elements of the kit, dedicated for specified device only. Never cut or shorten any cable, it may cause damage to your device. Use the cables delivered by VIGO. In case of OEM systems, make sure the the cables match the specifica tion of the controller. Turn off the power supply before plugging / unplugging cables. Avoid static discharges. MTCC-01 controller is an OEM type, so it is not equipped with the case. Provide the proper shielding and avoid touching the module while working. MTCC-01 module doesn't require forced cooling, although keep the radiator not covered and allow the air to flow the module. Important note! If you are setting up own system supplied by the the custom power supply, please make sure, the voltage/current matches to the values of the TEC and the IR detector. 11
