Apparatus for the simultaneous detection of ranges of wavelengths
First Claim
1. Apparatus for the simultaneous detection of several ranges of wavelengths of polychromatic light radiation, comprising:
- optical guidance means for guiding an incident polychromatic light beam, said optical guidance means comprising;
means including a first system of mirrors located in the path of the incident polychromatic light beam for collimating said polychromatic light beam into a hollow-cylindrically collimated light beam, wherein one mirror of the first system of mirrors is mounted at the center of the collimated light beam, andmeans including a second system of mirrors, said second system including a plurality of deflecting mirrors located in the path of the hollow-cylindrically collimated light beam, for deflecting the collimated light beam essentially perpendicularly in respect to a conceptual outer surface of a hollow cylinder defined by the collimated light beam and radially in respect to the longitudinal axis of the hollow cylinder;
a photo-detector for each range of wavelength to be detected, said photo-detectors being mounted opposite the deflecting mirrors; and
a common interference filter which filters the ranges of wavelengths to be detected out of the polychromatic light beam, said common interference filter being mounted in a path of the collimated light beam between the deflecting mirrors and the photo-detectors, the deflecting mirrors and the associated photo-detectors being pivotal about the interference filter;
said filtered ranges of wavelengths depending on the orientation of the deflecting mirrors in relation to the interference filter.

Abstract
An apparatus for the simultaneous detection of several ranges of wavelengths of polychromatic light radiation, using one detector for each detected range of wavelengths, includes an interference filter which filters the range of wavelengths to be detected out of the polychromatic light beam, and optical elements for guiding the polychromatic light beam to be detected. The optical elements include a first system of mirrors in the path of the incident polychromatic light beam for collimating it in a hollow-cylindrical manner, one mirror of the first system of mirrors being located at the center of the collimated light beam. The optical elements further include a second system of mirrors in the hollow-cylindrically collimated light beam that deflects this light essentially perpendicularly to the conceptual surface of the hollow cylinder and radially to the longitudinal axis of thereof. Photo-detectors associated with the particular deflection mirrors are mounted opposite the second system of mirrors to receive the deflected light. A common interference filter is mounted in the path of the beam between the deflecting mirrors and the photo-detectors, the deflecting mirrors and the associated photo-detectors being pivotable about the interference filter.
