METHOD FOR DETECTING AND CONTROLLING SUPPLY OF AN IMMERSION MEDIUM

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.

1. A method for detecting and controlling a supply of an immersion medium into an immersion film region disposed between a front lens of a microscope objective of a microscope having an autofocus device and a preparation being examined with the microscope, by using a light source reflected into a microscope beam path of the microscope with a beam splitter, the method including:
recording and evaluating a state of the immersion film region with a detection unit of the microscope or a detection unit of the autofocus device, using an autofocus signal of the light source or a reflection of a modulation object arranged in an intermediate image plane of an incident light illumination source; communicating the state of the immersion film region to a control unit; and using the control unit, changing a characteristic of the supply of the immersion medium based on the state of the immersion film region.
