Abstract
A radiation shield for near-infrared detectors of the type used in Raman spectroscopic systems comprises a chamber enclosing the detector and a cooling device in thermal contact with the chamber and the detector to reduce the level of unwanted radiation to which the detector would otherwise be exposed. The chamber may include a window in optical alignment with the detector, and the window may include one or more coatings to pass wavelengths in a range of interest or block radiation at wavelengths outside of this range. The shield may be enclosed in an evacuated dewar having a window which may also include one or more coatings to favor the wavelength range.
