Strey light

WebFor that purpose, optimized black coatings can be used. This is particularly important for applications where faint spectral components need to be detected in the presence of strong light at other wavelengths – for example, in Raman spectroscopy. Similarly, in imaging applications it is desirable to suppress a stray light as much as possible. Optical measuring instruments that work with monochromatic light, such as spectrophotometers, define stray light as light in the system at wavelengths (colors) other than the one intended. The stray light level is one of the most critical specifications of an instrument. For instance, intense, narrow absorption bands can easily appear to have a peak absorption less than the true absorption of the sample because the ability of the instrument to measure light transmission thr…
