The AvaSpec-TEC spectrometers are a special version of the standard AvaSpecs, where the CCD detector is mounted on a one-stage Peltier cooling device. This Peltier cooling element can reduce the temperature of the CCD chip by -20 °C, improving the dynamic range by at least a factor of 10. As an additional benefit from the cooling, the dark noise is reduced by a factor of 2-3.
The above features enable the AvaSpec-TEC to be implemented in low light-level applications, such as fluorescence and Raman measurements, where integration times of more than 5 seconds are needed. The AvaSpec-TEC can be delivered with 2 different TE cooled detector arrays with (2048/3648 pixels) as 1- or 2-channel instrument and has all the standard options, gratings and specifications the standard AvaSpec has.
The AvaSpec-TEC is built into a desktop housing, has a cooling fan to actively ventilate the heatsink of the Peltier cooling element and an internal power supply.
The AvaSpec-2048/3648TEC for the USB2 platform has an integrate temperature regulator.
