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. The positioning system (122) comprises at least one of the following systems: a camera system, particularly a monocular or binocular camera system, having at least one camera (410; 910); an image recognition system; a triangulation system; a propagation time measuring system, particularly for 1-, 2- or 3-dimensional propagation time measurement, particularly using at least one laser and/or at least one phase mix detector (PMD); a 1-, 2- or 3-dimensional intensity measuring system for at least one signal; a 2- or 3-dimensional magnetoresistive measuring system.
Abstract:
A photometric device (18) for quantifying a nucleic acid in a sample (518) in a tube (58), comprises a light emission unit (28), a sample obtaining unit (38) for holding the tube (58) with the nucleic acid sample (518) and a detection unit (48) wherein the sample obtaining unit (38) is arranged in between the light emission unit (28) and the detection unit (48) in particular, the light emission unit (28) and the detection unit (48) are arranged to provide light through the sample obtaining unit (38) such that light of a first wavelength of about 230 nanometers and light of a second wavelength of about 260 nanometers are simultaneously detectable within the detection unit (48). The photometric device (18) allows for efficiently analysing the nucleic acid sample by only considering invisible light. In particular, content of nucleic acid such as particularly a RNA or a DNA and a nucleic acid/salt ratio can simultaneously be determined such that efficiency of quantification of the nucleic acid sample (518) can be increased. Furthermore, since in addition thereto the sample obtaining unit (38) is arranged to hold the tube (58) or cuvette and the light directly passes the sample (518) being arranged in the tube (58) or cuvette, loss of sample, contamination of sample, need of additional sample treatment equipment such as pipettes or additional tubes as well as frequent cleaning of optics of the photometric device can be printed or reduced.

Abstract:
In an apparatus for the transport of the light emitted by a short-arc lamp (1) through its light outlet hole (13) to a desired location a number of light guides (5) are provided the light entry surfaces (50) of which are arranged at a predetermined location. In addition, a coupling element (3) is provided, which is arranged at a distance from the light outlet hole (13) of the short-arc lamp (1) and between the light outlet hole (13) and the light entry surfaces (50) of the light guides (5). The coupling element (3) is designed such that it collects the emitted light and couples it into the light guides (5) through the light entry surfaces (50) of the light guides (5).
