Abstract: The present invention concerns an LED spectrometer operating without moving parts, according to the sweep principle, and appropriate to serve as a structural component in many kinds of spectroscopic concentration analysers. The design of the invention affords the advantage that, even at its minimum, the optical power of the LED spectrometer of the invention is about fivefold compared with designs of prior art. Furthermore, improvement of the efficiency of the LED radiation source and of that of the optics has brought a multiple augmentation in power to the wavelength spectrum sent out by the radiation source. In the design of the invention, concentrators (6) of non-imaging type are used to collimate the wavelength spectrum emitted by the LEDs (3).

Abstract: A portable light source comprises a lamp (10) contained in a lamp box (42), which is housed in a case (41) to significantly reduce the influences of ambient temperature. In other words, the deuterium lamp (10), likely to be influenced by temperature, is enclosed in a double shield structure including the case (41) as well as the lamp box (42). It is known that ultraviolet irradiation of the air generates ozone. To prevent ultraviolet rays from penetrating the cooling air, an ultraviolet window (69) of the lamp box (42) is provided on an extension light guide (70). As a result, the generation of ozone is controlled in the areas where ultraviolet rays exist in the case (41), effectively preventing the fluctuation of output light due to the generation of ozone.

Abstract: A modular hyperspectral thermal camera that combines a wide field-of-view with a low erroneous recognition rate is described. The modular hyperspectral thermal camera provides such low erroneous recognition rates without any requirement for cryogenically cooling the associated optical components. The modular nature of the hyperspectral thermal camera permits easy exchange of the optical components and so provides a device that is easily calibrated and varied in resolution. In addition the modular nature allows the hyperspectral thermal camera to be readily converted to a broad band thermal camera, a full field spectrograph or a thermal bandpass filter camera, as required.

Abstract: A diffraction grating for optical communication is disclosed. The diffraction grating includes a substrate and a reflective material adjacent the substrate, wherein one or more input optical signals incident the reflective material is diffracted into one or more output optical signals over a wavelength range of at least approximately 30nm, within which the diffraction grating is substantially polarization insensitive.

Abstract: This invention provides a method of determining a trace gas concentration in a gas sample utilising Fourier Transform Infra-Red Spectroscopy, said method comprising the following steps i) to iii) of: i) synthetically calibrating a spectrometer by the steps of: a) calculating a theoretical spectral response function for a series of candidate chemical substances; b) convolving said theoretical spectral response function with a spectrometer instrument response function corresponding to said spectrometer device so as to produce an expected response function for said series of candidate chemical substances; and c) utilising said expected response function as the calibration of said spectrometer device in the subsequent measurement of chemical substances; ii) determining a spectral window within which to fit a calculated spectral trace to an experimental spectral trace by the steps of: a) choosing a series of candidate windows; b) determining the likely error measure associated with a fitting of said spectral trace for each of said series of candidate window; c) utilising said likely error measure associated with each of said fitting to determine a final window having substantially the lowest likely error measure; and d) utilising said final window as said spectral window; and iii) utilising said calibration and said spectral window to fit a calculated spectral trace to a spectral trace measured by the spectrometer and to thereby determine the concentrations of constituent gases and/or the ratio of the concentration of one isotope isomer (i.e. isotopomer) to that of another isotopomer of the same molecular species.

Abstract: A portable colorimeter housing (100) has an upper portion (103) which is mounted on a lower portion (101) in a cantilever fashion and is adapted to receive sheets larger than the device for purposes of obtaining tri-stimulus color measurements. An adjustable paper guide (119) determines the distance that a sheet is inserted between upper (163) and lower (161) plates. A sheet to be measured inserted in the opening (109) will operate a micro switch (139) which activates a motor operative to advance the sheet between a motor driven drive wheel (135) in the lower plate (161) and an idler roller in the upper plate (171). Transmittance or reflectance measurements are taken by means of photodetector cells (242) including colorimetric filters. A user programmable processor performs pattern recognition and control functions.

Abstract: A diode array spectrophotometer has an entrance slit apparatus, a diffraction grating, a diode array and a casing to define the relative positions of these elements. The casing and the holder for accepting the diffraction grating are made of a ceramic whose coefficient of thermal expansion is adapted to that of the diode array. The grating holder has a cylindrical outer surface and is situated within a conic-frustum-shaped opening of the casing. Between the grating holder and the conic-frustum-shaped opening, there are a plurality of filler elements which are made of ceramic or glass.
