2.3. 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 possible to achieve temperature depends also

on ambient temperature and the heat dissipated by the detector due to the detector biasing. Considering all the

factors and preparing measurements with the conditions comparable with those in final application, detector are de-

scribed and the final temperature is set.

Thermistor being inside the detector gives the feedback about the IR sensor temperature and allows the con-

troller to perform the temperature control process. 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 measured and described, STCC-04 controller parameters (max current, depending on

the cooler) and final temperature are set, and the system is ready to work.

The STCC-04 module contains low noise and precise analog path, PID controller block, and the power stage

for Peltier element driving. It has also three diodes indicating supplying the controller, the actual state of the control -

ler (getting the temperature down / ready to work) and error (thermistor connection broken). 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 STCC-04 is a low noise controller and doesn't introduce noise and disturbances to the system.

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 properly connec-

ted 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 detecor 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.



4. STCC-04 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 exceeding 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 exposing to direct sunlight and strong UV/VIS light as this may result in degradation of a detector per-

formance

• Avoid electrostatic discharges (ESD)



5. Safety instructions

To ensure safe and failure-free operation of the STCC-04 controller, comply with the following precautions:

Before connecting the power supply to the mains, make sure it is compatible with the mains voltage and fre-

quency.

The power supply is intended for the indoor use.

Do not use the controller if the temperature and the air humidity extends the values valid for the STCC-04

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.

Do not exchange controllers between kits. Every controller is individually trimmed to the IR detector from the

kit. Internal STCC-04 construction varies due to the TEC stage number

Important note!

If you are setting up own system supplied by the the custom power supply adapter, please check if the

voltage/current matches to the values of the supply requirements of the STCC-04.
