The ImageQuant 350 and ImageQuant RT ECL systems are described as having “Thermoelectric Cooling”. How does this differ from the Peltier cooling?
Thermoelectric cooling and Peltier cooling are different terms to describe the same feature. back to top 5. In general, it is thought that the lower the cooling temperature, the better the sensitivity of the camera. The specification of ImageQuant systems often shows the cooling to be less than competitors? Cooling on CCD cameras is required to reduce the noise inherent in the camera, thus reducing the background and increasing sensitivity. Cooling temperature alone on the specification really does not mean much as the performance of the system depends on several factors. In general, you need to look at the read noise level, the dark current, and the full well capacity of the CCD chip. Higher quality CCD cameras have inherently low noise, so cooling is not as important. This is the case with the ImageQuant RT ECL. We do not need to cool the system as much because we have a better quality camera. The read noise and dark current on our ImageQuant RT ECL are insignificant (0.2 electrons/p
