Abstract: An spectrophotometer system (100) separately images rays of optical radiation in a plurality of wavelength bands from a distant object into a plurality of distinct wavelengths simultaneously and projects the separate images upon a detector (124). Each distinct wavelength is within a corresponding one of the plurality of wavelength bands. The apparatus includes a lens system comprising an objective lens (104), first and second field lenses (108, 116), a collimating lens (118), and a re-imaging lens (120) all disposed coaxially with respect to each other along an optic axis (110). The objective lens (104) and the first field lens (108) coact to cause rays of optical radiation emitted by the object to form an image at a first focal plane. An aperture (112) at the first focal plane passes rays of the optical radiation corresponding to a predetermined portion of the object. The second field lens (116) causes rays from the image at the first focal plane to form an image at a second focal plane. The collimating lens (118) causes rays entering the collimating lens (118) to be parallel leaving the collimating lens (118). The re-imaging lens (120) forms an image on the detector (124). A filter (114) between the first field lens (108) and the first focal plane passes rays of the optical radiation within the wavelength bands and suppresses optical radiation in wavelengths outside the wavelength bands. A prism system (122) is disposed coaxially along the optic axis near the second focal plane. A first prism (130) causes light in a first one of the plurality of wavelength bands to appear in a first location. A second prism (132) causes light in a second one of the plurality of wavelength bands to appear in a second location.

Abstract: A spot of a sample is illuminated by laser light. Raman scattered light is collimated in a parallel beam by a microscope objective, and analyzed by a dispersive or non-dispersive analyzer (such as a diffraction grating or filter). A lens then focuses the Raman scattered light onto a two-dimensional photodetector array in the form of a charge-coupled device (CCD). A confocal technique is described to eliminate light scattered from outside the focal plane of the objective. This may be done by binning together a few pixels of the CCD at the focal point of the lens, or by image processing techniques in a computer.

Abstract: A sample placed under a microscope is illuminated by light from a laser beam. Raman scattered light is passed back via a dichroic filter to various optical components which analyse the Raman spectrum, and thence to a CCD detector. The optical components for analysing the Raman spectrum include tunable dielectric filters in a filter wheel; a Fabry-Perot etalon; and a diffraction grating. These various components may be swapped into the optical path as desired, for example using movable mirrors, enabling the apparatus to be used very flexibly for a variety of different analysis procedures. Various novel analysis methods are also described.
