Does Your CCD Camera Need Cooling?

The answer may lie in how much noise is generated by dark current.

David W. Gardner

To those in the light-starved world of astronomy, the result of cooling cameras to ultralow temperatures is obvious: Truly amazing images can be produced in situations where only a few photons are available. The need for cooling may not be so obvious in applications such as web inspection, laser profiling and medical imaging. Yet even here, cooling the camera (albeit not to cryogenic levels) can often provide a dramatic boost to image quality. In most cases, the benefits of cooling come from its ability to reduce the dark current generated by the camera. This pesky current represents the...Read full article
