Claim Text:
1. Infrared spectrometer for detecting an infrared spectrum of light received from an object, comprising: a wavelength converter system comprising a nonlinear material and having an input side and an output side, the wavelength converter system comprising at least a first up-conversion channel and a second up-conversion channel, the wavelength converter system being arranged such that light traversing the wavelength converter system at different angles in the nonlinear material is imaged into different positions in an image plane, a demultiplexer configured for demultiplexing light in the first up-conversion channel and light in the second up-conversion channel, the demultiplexer being located on the first side of the wavelength converter system, and a spatially resolved detector arranged in the image plane to detect light in the first output wavelength range and second output wavelength range output of the wavelength converter system.
