TE-Cooled Spectrometers
The AvaSpec-2048TEC is a special version of the AvaSpec-2048, where the Sony 2048 CCD detector is mounted on a one-stage Peltier cooling device.
This Peltier cooling element can reduce the temperature of the CCD chip by ca. 30 °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-2048TEC to be implemented in low light-level applications, such as fluorescence and Raman measurements, and where integration times of more than 5 seconds are needed.
The AvaSpec-2048TEC can be delivered as a single or dual channel instrument and has all the standard options, gratings and specifications as the standard AvaSpec-2048.
The AvaSpec-2048TEC 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.
