ABSTRACT:
An optical system for receiving an incoming beam of electromagnetic radiation, for dividing it into a transmitted beam, containing a part of the wavelength band of the incoming beam, and a reflected beam, containing the remainder of the wavelengths in the incoming beam, and for transferring the transmitted beam continuously to a detector. The system is capable of switching the reflected beam between any one of two or more detectors. The system comprises an objective lens, a dichroic beamsplitter cube, a first detector, capable of detecting radiation in a first wavelength band, a second group of two or more detectors, each capable of detecting radiation in a second wavelength band and means of rotating the dichroic beamsplitter cube, so as to switch between the detectors of the second group.
