Stray Light Correction
Correction matrix for the reduction of stray light in the spectrum
How does an array spectroradiometer almost reach the stray light level of a double monochromator?
The most significant limitation in the performance of an array spectroradiometer in photometry and radiometry is the incidence of stray light in the instrument. In other words, a certain element of the array detector is contaminated by radiation from a spectral range other than specified. In the CAS series of powerful array spectroradiometers from Instrument Systems, stray light is effectively suppressed by design measures, so that contamination is low from the outset.
Stray light corrected CAS 140D – the array spectroradiometer with the highest optical dynamism and accuracy
Use of a stray light correction matrix in the calibration process (optional) further optimizes the good stray light values of the CAS 140D. The measuring instrument is thus ideally suited, among others, to accurate measurement of UV-LEDs and determination of the hazard class of light sources (photobiological safety).
