What is Pixel Well Depth?

May 25, 2017 | Detectors, Glossary of Spectroscopy Terms, Uncategorized

Pixels work by converting photons into electrons. Most detectors store electrons in the pixels while they are exposed to the light, then convert the electrons into a signal after exposure. The pixel well depth, also called the full well capacity, determines how many...

What is a Hot Pixel?

May 23, 2017 | Detectors, Glossary of Spectroscopy Terms

A hot pixel has a higher than average dark current. This can be accounted for in the dark spectrum or by cooling. However, if the dark current is too large, the pixel might saturate prematurely. If that is the case, the pixel can be considered defective and...

What is Pixel Resolution?

May 23, 2017 | Detectors, Glossary of Spectroscopy Terms, Spectrograph

Pixel resolution is simply the dimensions of the detector in pixels. For StellarNet detectors, the CCD is 2048 x 1 pixels and the PDAs are 512 x 1 or 1024 x 1 pixels. Notice that they are all linear detectors. Computer monitors and TVs are also described according to...
