Single step to Multistage - the simple way to increase cooling level in detector applications
Jan 8, 2010
TEC Microsystems GmbH introduces 2-stage thermoelectric cooler designed for simple substitution of standard single-stage 8x8mm TE coolers in various detector applications to archive higher cooling level. 8x8mm thermoelectric cooler on TO-8 style header is the one of typical solutions for X-Ray detectors and some IR sensing applications. In many cases a single-stage TEC provides enough cooling level for IR or X-Ray detector. However, the trend for signal resolution increasing and noise reducing may require lower operating temperatures, where two-stage TE cooler is more optimal.

Usually switching for another TEC is connected with constructional and power supply updates in already developed application. Two-stage TE cooler may differ by height, cold side dimensions and require different power consumption.
TEC Microsystems GmbH provides optimized version of 2-stage TE cooler, that has the same dimensions and power consumption as typical 8x8mm single stage type, which is very standard for many IR and X-Ray detector applications. The advantage of such solution is in very simple switching for 2-stage TE cooler in already existing design, without additional developments or constructional updates. Detector manufacturer may simply substituteВ single stage thermoelectric cooler in existing design and get up to 20 degrees deeper cooling level.
The solution proposed is based on 2MX04-043-0510 thermoelectric cooler with mixed ceramics plate thicknesses to fit in a height of standard single-stage TE cooler. 2MX04-043-0510 datasheet is available by this link. Or, please, click here to get the datasheet of TE Sub-assembly based on standard TO-8 12pin header. 2MX04-043-0510 thermoelectric cooler can be provided separately or mounted on standard TO-8 headers. Mounting on Customer's headers is also provided.
