摘要:
The invention relates to an arrangement for spatially resolved and wavelength-resolved detection of light radiation which is emitted from at least one OLED (1) or LED. A multilayer system (2), which is formed with layers configured on top of each other in an alternating manner made of a material with higher and lower optical refractive index n, is arranged between an electrode (3, 4), an OLED or LED and a substrate. In this case, light radiation from the at least one OLED or LED, comprising a plurality of different wavelengths λ1, ⋋2, ⋋3,...⋋n, exits the multi-layer system. Light radiation, comprising different wavelengths λ1, ⋋2, λ3,...⋋n with defined angles, exits, and is incident on at least one detector array (9, 9.1) after at least simple refraction on an optical element (10, 11) or after reflection on a layer or a layer system of a sensor (12), such that each light radiation comprising a wavelength λ1, ⋋2, ⋋3,... or ⋋n is incident on a detector element of the detector array. The detector elements of the detector array are arranged discretely in relation to one another.

A reflective beam shaper (100) for producing a desired emission characteristic from an emission characteristic of a surface light source (105) comprises a beam shaping areal structure (110) having a plurality of light-transmissive beam shaping openings (115) extending from a first side (112), which is to face the surface light source, to a second side (114), which is opposite the first side, through the beam shaping areal structure, wherein the light-transmissive beam shaping openings have reflective side walls (117), and wherein a lateral extent (L1) of the light-transmissive beam shaping openings on the first side of the beam shaping areal structure is smaller than a lateral extent (L2) of the light-transmissive beam shaping openings on the second side of the beam shaping areal structure, such that the emission characteristic of the surface light source is changed to the desired emission characteristic upon passage through the beam shaping areal structure.
摘要:
The invention relates to an arrangement and a method for the optical detection of chemical and biochemical molecules and/or particles contained in samples, using surface plasmon resonance (SPR) which varies according to the optical refractive index. According to the invention, light from a light source is directed towards an optical detector by means of at least one sensor element which is embodied as an optical waveguide, at least in sections. At least one electroconductive thin layer is provided on the boundary surface of said optical waveguide, beneath a measuring surface. The light guided by the optical waveguide strikes the boundary surface in the region of the thin layer, at angles above the total reflection angle. A front side of the sensor element is provided with an aspherical, convex, optical surface for the light incidence, by which means the light inside the sensor element is focussed in the direction of the boundary surface covered by the at least one thin layer and/or measuring surface, and a second aspherical, convex, optical surface is provided on the front side of the sensor element for the light emergence. The light modified as a result of surface plasmon resonance is directed in a collimated form towards the at least one optical detector by means of said optical surfaces.

The invention relates to a device for detecting biochemical or chemical substances by fluorescence excitation and a method for its production. This method can be applied in various areas, for example in biotechnology, molecular biology, in the development of pharmaceuticals as well as for analysing various chemical substances. With this relatively simple device, detection of a large number of samples can be carried out quickly and with a high degree of precision. To this end, a plate-shaped substrate (1) with locally defined structure is used for detecting the different samples (5). A lens array (2) fitted on detector side and configured in accordance with the structure is preferably used to image the fluorescent light of the different samples on a detector array. A detector array adapted to the structure of the substrate can also be placed or mounted on the substrate.
