Abstract: A Raman spectroscopy apparatus comprises an imaging optical system that transmits light from an object to a spectrograph along an optical path. A scanning device intersects, and is movable with respect to, the optical path. Light is directed onto the scanning device to illuminate the object at a plurality of illumination points. The imaging optical system transmits Raman scattered light emitted from the object at the illumination points to an intermediate image plane, the scanning device being located at the intermediate image plane, and transmits the Raman scattered light from the intermediate image plane to the spectrograph. In comparison with conventional confocal Raman spectroscopy, the apparatus can perform Raman analysis of a sample more quickly, and in comparison with conventional line scan Raman spectroscopy the apparatus can perform Raman analysis more accurately.

Abstract: A Raman analysing apparatus comprises an imaging optical system for imaging an object along an optical path to an optical detector, an irradiation optical system for illuminating the object, and a scanning device comprising a spinning pinhole disk. The irradiation optical system directs light onto the scanning device to illuminate the object at a plurality of illumination points. The imaging optical system images Raman scattered light emitted from the object at the illumination points to an intermediate image plane at which the scanning device is located. The imaging optical system may include a spectral filter and/or at least one optical spectral analyser. The apparatus enables high speed confocal Raman imaging and/or high speed confocal Raman spectography to be performed.

Abstract: The invention concerns a system for obtaining characteristic spectral information of light emitted from an optical fibre (10). The system comprises an optical spectrograph (12, 13, 14, 15) and a detector (16, 17). The spectrograph comprises a diffraction grating (13) that diffracts light in the wavelength band 800 - 1,700 nm, or parts thereof, into spectral orders in one plane of spreading, and a wavelength dispersing means (14) that spreads the wavelength components in a plane of spreading that is perpendicular to the first plane of spreading. A digital camera (17) with a detector surface (16) records the images of the light, and a computer (19) converts the signals into a spectrum and calculates magnitudes that are characteristic of the optical fibre (10), for a light source (21) that illuminates the fibre and/or for other electro-optical components that are used in optical telecommunication.

Abstract: A microscope for performing differential phase contrast (DPC) microscopy comprises an infinity-corrected microscope objective and a tube lens, and at least one lens configured to image a back focal plane of the microscope objective to a conjugate back focal plane outside of the microscope objective. An aperture stop is located at said conjugate back focal plane. The object plane is located between the objective and the illumination source, the illumination source being configurable to illuminate the object from any one of a plurality of locations that are angularly displaced about an axis that is perpendicular to the object plane. The illumination source is placed at a working distance from the object to allow the user unrestricted access to the specimen area. The microscope may use a standard objective, which reduces cost.

Abstract: A support assembly for a heat pump system comprising a base (34) and a plurality of platforms (36) for supporting a respective heat pump such as a thermoelectric cooler (14). Resiliently flexible pipes support the platforms with respect to the base and form part of a coolant circulation system. The platforms are movable with respect to each other and the support structures allow the platforms to move with respect to the base. An object to be cooled (12), such as an image sensor, is mounted on the heat pumps. The platforms are able to move in response to expansion and contraction of the object thereby preventing damage to the heat pump system.
