What is Spectrometer Dark Current?
Sometimes thermal fluctuations have enough energy to generate electrons in the same way that photons do. These electrons are not part of the signal, but there is no way to distinguish them from the signal in the detector, so they become a source of noise. The dark...What is a Popping Pixel?
Popping pixels in spectrometers have a dark current that changes abruptly, likely due to defects in the pixel. It is the most disruptive type of defective pixel because it is unpredictable. There is no way to account for the behavior, so a popping pixel must always be...What is a Dead Pixel?
Dead pixels in spectrometers have significantly lower responses than nearby pixels. If pixels are merely weak instead of completely dead, they can be accounted for in the system sensitivity curve. However, this will decrease S/N. If this becomes a problem, the dead...What is a Defective Pixel?
A defective pixel in a spectrometer is a pixel that doesn’t behave as it should to the point of being unusable. This includes dead pixels, hot pixels, and popping pixels. The SpectraWiz software can account for defective pixels and will interpolate a value...What is Pixel Well Depth?
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...
