Calibration standard for a device for image-based representation of biological material

Abstract

The invention relates to a calibration standard () for a device () for image-based representation of biological material () which is excited to luminescence at least regionally during the examination. The device () has an illumination unit () comprising a radiation source, by which an electromagnetic excitation radiation () is emittable. Furthermore, a receptacle () is provided, which ensures that the biological material () arranged on a carrier () is positioned within a beam path of the excitation radiation (). Moreover, the device has at least one image generating unit (), which receives luminescence radiation () emitted by the biological material () on account of the excitation by the excitation radiation () and generates an image at least of the regions of the biological material () which are excited to luminescence. For calibration purposes, the device has a calibration standard (), which emits a calibration radiation on account of the excitation by the excitation radiation (), which calibration radiation is captured by the image generating unit (), and a calibration signal is generatable in a controller () taking account of the captured calibration radiation. The technical solution described is distinguished by the fact that the calibration standard () has a housing () with, enclosed therein, a substance () which is excitable to luminescence, and is fixedly connected to the illumination unit () or the receptacle () with the aid of a fixing means ().
