Abstract: The invention concerns fluorescence standards, and in particular fluorescence standards for calibrating optical detectors. According to the invention, a fluorescent mineral or mixtures of minerals are employed for use as a fluorescence standard. The fluorescent mineral can be a naturally occurring mineral or a synthetically produced mineral. Preferred fluorescent minerals for use as fluorescence standards are corundum, fluorite, turquoise, amber, zircon, zoisite, iolite or cordierite, spinel, topaz, calcium fluorite, sphalerite or zincblende, calcite or calcspar, apatite, scheelite or calcium tungstate, willemite, feldspars, sodalite, a uranium mineral, a mineral containing Al3+, and in particular ruby and sapphire.

Abstract: A sample holder, such as a microscope slide, is provided in the form of a card-shaped substrate or plate, preferably for use in an analytical reader. The sample holder comprises at least one hole, preferably a plurality of holes, for receiving a sample to be analyzed. The at least one hole extends completely through the substrate and is sized such that the sample is held within the at least one hole by means of the surface tension of the sample against the force of gravity. Optionally the substrate comprises a first upper substrate and a second lower substrate that together embed a porous membrane. As a further option the sample holder comprises a first cover attached to the top side of the first upper substrate and/or a second cover attached to the bottom side of the second lower substrate.

Abstract: The invention proposes a manual measuring appliance (112) and an analytical measuring system (110) which can be used to measure at least one analyte in an eye fluid of an eye (114). The handheld measuring appliance (112) comprises a measuring system (120) and a positioning system (122). The measuring system (120) can measure at least one property of the at least one analyte and/or at least one analyte-dependent change of property of at least one ocular sensor (116) in the eye fluid, and this can be used to infer a concentration of the analyte in the eye fluid. The positioning system (122) is set up to measure a spatial positioning, wherein the spatial positioning comprises a distance between at least one measurement location in the eye (114) and the handheld measuring appliance (112) and also furthermore at least one further positioning co-ordinate.

Abstract: The present invention relates to a hand-held fluorescence photometer and method for measuring an analyte level, preferably a blood glucose level, from an ocular fluid. The photometer is based on a dual beams measuring system and it is capable of defining the correct positioning for the measurement. Only when the apparatus is correctly positioned the actual analyte measurement automatically takes place.

Abstract: In a process for the production of mouldings, e.g. contact lenses, a starting material which contains a photoinitiator with a spectral absorption (AC) in a given wavelength range is exposed to a predefined amount of light of a wavelength from this given wavelength range. Polymerisation and/or crosslinking of the starting material is thereby initiated, and in this way a demouldable moulding is formed The intensity of light is measured, to which end a broadband photoreceiver (511) is used, in front of which receiver a filter (510) is arranged, the transmission (TC1, TC2, TC3; TC4) of which is designed such that the light passing through the filter (510) and impinging on the photoreceiver (511) corresponds in its intensity to the light absorbed by the photoinitiator based on its spectral absorption (AC) at the wavelength from the given wavelength range.

Abstract: A method and an apparatus are proposed for producing mouldings, in particular ophthalmic lenses, such as contact lenses for example, in which a starting material located in a mould (100, 110; 100a, 110a) is polymerized and/or crosslinked by means of exposure to light, in particular by exposure to UV light, so that a demouldable moulding is produced. The measurement of the intensity (I) of the light takes place during the production of the mouldings.
