WebEtaloning is particular to back-illuminated sensors and is caused by interference between reflections off the front and back parallel sensor surfaces. For NIR applications, such as imaging of Bose Einstein Condenates, etaloning effects, often observed more notably beyond ~ 750nm, can sometimes restrict the ability to perform high integrity ... WebSpectroscopic etaloning is related to, but different from, spatial etaloning. It derives from the fact that in a spectrometer the wavelength of light varies across the CCD. Thus, even …

WebMay 1, 2013 · First, this process greatly increases the cost of production, and second, there can be problems caused from reflections off the front and back surfaces of the detector (etaloning effect) because the detector is so thin. This effect can be mitigated by processes such as deep depletion, but these add additional cost to the manufacturing … WebSpectroscopic etaloning is related to, but different from, spatial etaloning.
