Coverslipping machine having an optical limit fill level measuring device for a liquid

摘要

The present invention relates to a coverslipping machine (1) including: a hollow needle (2) for applying mounting medium onto a specimen slide (5); a transparent container (103) to be filled with a liquid; a light source (101) for radiating measurement light in a principal radiating direction (A) into the container (103); and a light sensor (102, 102′) for detecting the measurement light, the light source (101) being arranged with respect to the container (103) in such a way that the radiated measurement light is refracted by a liquid in the container whose fill level exceeds a fill level limit, the light sensor (102, 102′) being arranged with respect to the container (103) in such a way that only measurement light refracted by the liquid or only measurement light not refracted by the liquid is detected.

1. A coverslipping machine (1), comprising:
a hollow needle (2) for applying mounting medium onto a specimen slide (5); a transparent container (103) to be filled with a liquid; a light source (101) for radiating measurement light in a principal radiating direction (A) into the container (103); and a light sensor (102, 102′) for detecting the measurement light; wherein the light source (101) is arranged with respect to the container (103) such that the radiated measurement light is refracted by the liquid in the container whose fill level exceeds a fill level limit; wherein the light sensor (102, 102′) is arranged with respect to the container (103) such that measurement light refracted by the liquid or measurement light not refracted by the liquid is detected; wherein the container (103) is configured to receive the hollow needle (2); wherein in a working position in which the mounting medium is applied onto the specimen slide (5), the hollow needle (2) is located above the container (103).
