2.12 AvaSpec-2048TEC Thermo-electric cooled Fiber Optic Spectrometer
AvaSpec-2048TEC
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 degrees 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, where integration times of more
than 5 seconds are needed. The AvaSpec-
2048TEC can be delivered as one or 2-channel instrument and has all the standard options, gratings
and specifications the normal AvaSpec-2048 has.
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.
