摘要： A method for detecting and controlling supply of an immersion medium into an immersion film region between the front lens of a microscope objective and a preparation, particularly in automated microscopes, using a light source which is reflected into the microscope beam path by means of a beam splitter. The state of the immersion film region is recorded and evaluated in a detection unit of the microscope or a detection unit of the autofocus device through an autofocus signal of the light source and/or a reflection of a modulation object arranged in the intermediate image plane of an incident light illumination, and is transmitted to a control unit for the purpose of a change or an error treatment of the immersion process.

摘要： A microscope including an objective having a focal plane in a sample space, and an autofocus device comprising a light modulator for generating a luminous modulation object that is intensity-modulated periodically along one direction, an autofocus illumination optical unit that images the modulation object such that its image arises in the sample space, an autofocus camera, an autofocus imaging optical unit that images the image of the modulation object in the sample space onto the autofocus camera, a control device, which receives signals of the autofocus camera and determines an intensity distribution of the image of the modulation object and generates a focus control signal therefrom. The control device determines an intensity distribution of the image of a luminous comparison object imaged by the optical unit to correct the intensity distribution of the image of the modulation object with regard to reflectivity variations in the sample space.

摘要： A microscope includes a holder for holding a sample, an objective for imaging at least apart of a sample held by the holder, a detection module, a control unit for setting the focus position of the objective in a first direction for the recording by means of the detection module, and a focusing module for maintaining a set focus position of the objective. The focusing module includes the control unit, a second detector and first focusing optics with adjustable focal length. The focusing module is switchable into a focus-hold mode, wherein an intensity-modulated object is imaged into the sample via the first focusing optics and the objective, and an image of the imaged object is recorded by means of the second detector. The control unit holds the focus position of the objective on the set focus position, based upon the recording of the second detector.
