Detectors
Choosing the right detector could be the most important decision when specifying a spectroradiometer. From our experience gained in producing hundreds of spectral measurement systems, we have assembled a range of detectors to cover most applications. Each detector is properly housed, complete with any associated circuitry and can be mounted directly at the exit slit of any of our monochromators. The table lists our standard range, but Bentham has working knowledge of many others, including sandwich types, so please consult us if you do not see the detector that you want.
