Abstract: An optical filter is disclosed including two laterally variable bandpass filters stacked at a fixed distance from each other, so that the upstream filter functions as a spatial filter for the downstream filter. This happens because an oblique beam transmitted by the upstream filter is displaced laterally when impinging on the downstream filter. The lateral displacement causes a suppression of the oblique beam when transmission passbands at impinging locations of the oblique beam onto the upstream and downstream filters do not overlap.

Abstract: A spectrometer comprises a plurality of isolated optical channels comprising a plurality of isolated optical paths. The isolated optical paths decrease cross-talk among the optical paths and allow the spectrometer to have a decreased length with increased resolution. In many embodiments, the isolated optical paths comprise isolated parallel optical paths that allow the length of the device to be decreased substantially. In many embodiments, each isolated optical path extends from a filter of a filter array, through a lens of a lens array, through a channel of a support array, to a region of a sensor array. Each region of the sensor array comprises a plurality of sensor elements in which a location of the sensor element corresponds to the wavelength of light received based on an angle of light received at the location, the focal length of the lens and the central wavelength of the filter.

Abstract: Diffuse reflectance spectroscopy apparatus for use in analysing a sample comprising a sample receiving location (2) for receiving a sample (3) for analysis; an illumination arrangement (4) for directing light towards a received sample; a detector (6) for detecting light reflected by a received sample; and collection optics (5) for directing light reflected by a received sample towards the detector. The illumination arrangement further comprises an interferometer (42) and a half beam block (45a, 45b) which is disposed substantially at a focus in the optical path for blocking light which exits the interferometer, passes said focus, and is reflected from reentering the interferometer. A half beam block (45a) may be disposed in the optical path between the interferometer and the light source (41) for blocking light that exits the interferometer back towards the light source and is reflected by the light source from re-entering the interferometer and/or a half beam block (45b) may be disposed in the optical path on the opposite side of the interferometer than the light source.
