getSpec-2048-COOL - peltier cooled UV/VIS/NIR spectrograph
Request for information
The getSpec-2048-COOL is a special version of the getSpec-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 getSpec-2048-COOL 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 getSpec-2048-COOL is built into a desktop housing, has a cooling fan to actively ventilate the heat sink of the Peltier cooling element and an internal power supply.
