Abstract: A device for analysing a product to be analysed which is located in a product space having a probe body arranged in a probe housing and having a peripheral wall, and at least one radiation source and at least one optical receiver. At least one measurement window in the probe body has an entry region and an exit region for measurement radiation. An evaluation unit is also provided. The probe body can be brought into a measurement position, in which at least one part of the probe body in which the measurement window is located penetrates through an opening of the probe housing into the product space for the analysis. In addition, the probe body can be brought into a retracted position, in which the probe body is still located at least partially in the region of the opening of the probe housing and thus covers the opening.

Abstract: A specimen slide (1) for a microscope, camera or other such observation device has a receiving area (2) for cell or tissue samples or other such organic material and a smaller observation area (3) for the organic material. The specimen slide (1) at least in the observation area is made of transparent material. Within the receiving area (2) the specimen slide (1) is provided with thin-film sensors (6 to 12) adjacent to the observation area (3) for measuring physiological parameters of the organic material. The chemical and physical characteristics of the organic material under observation can be picked up by the sensors while it is observed, for example under a microscope. Sensors of differing types can be provided, such as interdigital capacitors (6), NO sensors (8), O.sub.2 sensors (9) or temperature sensors (11), thereby making available important physiological measurement and/or control parameters.
