The illumination device including at least one emission source, the illumination device being configured to guide emission light generated by the emission source through the intermediate space. The detection device including at least one detector configured to measure light signals received from the intermediate space; and the detection device includes an angle-dependent filter arranged between the illumination device and the at least one detector in a beam path of the emission light, the angle-dependent filter being configured to substantially only let through light beams having an angle of incidence smaller than a predetermined critical angle.

Abstract: A transmission device for examining samples in cavities of a microtiter plate, the transmission device including: an illumination device; and a detection device, an intermediate space being formed between the illumination device and the detection device, the intermediate space being configured to receive a microtiter plate. The illumination device including at least one emission source , configured to generate emission light. The illumination device being configured to split the emission light generated by the at least one emission source onto a plurality of partial beam paths, each extending as a transmission beam path through the intermediate space to a corresponding detector of the detection device; and the detection device being configured to measure light signals incident along each of the transmission beam paths by the corresponding detector.

Abstract: A device for optically representing intraocular pressure, having an arrangement which is implanted into the eye with a membrane that curves outwards when the intraocular pressure changes, and a contact surface, these altering the polarization for a spectral range of incident and reflected light in the region of their contact with one another, as well as a read-out arrangement that optically reproduces a planar image of the light which is reflected by the photonic crystal and whose polarization has been altered, and that comprises a polarization filter for the irradiated light and the light reflected by the photonic crystal. Also, a method for measuring intraocular pressure.

Abstract: The invention relates to a device for detecting biological materials, comprising a light source (1) that radiates light (2) into an object (5), a photonic crystal brought into contact with the object, a detector (8) that detects light (7) transmitted through the photonic crystal (6) and the object, a first polarization filter (3) arranged between the light source (1) and the photonic crystal (6), and a second polarization filter (4) arranged between the object (5) and the detector (8) and rotated 90° relative to the first polarization filter (3), wherein the source (1) and the photonic crystal (6) are matched to each other such that the resonances caused by the photonic crystal (6) and the resonances caused by the interaction of the photonic crystal (6) with the object (5) lie in an edge range of the emission spectrum of the light source (1).
