    摘要： A radiation detection system (100) is described comprising a measurement region (104) in a measurement chamber adapted for receiving at least one sample (108) to be examined and adapted for receiving excitation radiation for impingement on the at least one sample (108) and for generating sample radiation. The radiation detection system (100) furthermore comprises at least one detector element (106) for detection of the generated sample radiation. The radiation detection system thereby is a front irradiation system, i.e. the excitation radiation is incident on a first side of the measurement region (104) in a measurement chamber and the at least one detector element (106) is positioned at a second side of the measurement region (104) in a measurement chamber, the second side being opposite to the first side with respect to the measurement region (104) in a measurement chamber, such that detection occurs at the side facing the first side. The detection system (100) also comprises optical means (112) adapted for guiding said excitation radiation aside the at least one detector element (106).

    摘要： A detection system (100, 150, 180, 200, 220, 250) for detecting luminescence from at least one sample (108) when excited by incident excitation radiation. Detecting luminescence may allow to detect, for example, biological, chemical or bio-chemical particles. The detection system (100, 150, 180, 200, 220, 250) comprising at least one optical component (102) with at least a first surface (104). The first surface (104) of the at least one optical component (102) is located to internally reflect incident excitation radiation to create an evanescent field outside the at least one optical component (102) for exciting the at least one sample (108). The detection system also comprises at least one detector element (110) that is in direct contact with the at least one optical component (102) to detect the luminescence from at least one excited sample (108) through the at least one optical component (102).

    摘要： The present invention provides a sensor and a method for detecting an optically variable molecule (9) in a sample (3). The sensor comprises an excitation radiation source (1) for irradiating the sample (4) and exciting the optically variable molecule (9), thus generating a luminescence signal (7). The sensor furthermore comprises a modulation means (4) for modulating the excitation radiation beam (2) in a direction different from, preferably substantially perpendicular to, a scanning direction of the excitation radiation beam (2) over the sample (3). The method and sensor according to the invention lead to an improved signal-to-noise ratio by reducing and even minimising the background signal in the luminescence signal (7) and to an improved accuracy by minimising signals coming from false-positives.

    摘要： An illumination detection system comprises an excitation radiation source and associated radiation processing arrangement, and a focusing arrangement for focusing the excitation radiation from the radiation processing arrangement onto an analysis region of a sample. A radiation collection arrangement collects radiation from the analysis region of the sample resulting from the excitation, and a detector detects the collected radiation. The focused excitation radiation comprises an excitation line which is evanescent in the sample. This combines the advantages of line scanning (reduced analysis time) and evanescent excitation (reduced background signal) and therewith enables increased measurement speed and precision for point of care application.
