Abstract: The invention refers to a deflection module comprising a first deflection unit (10a) comprising a first scanning device (12a) for scanning a first working beam (50a) over a first working field and (40a) and a second deflection unit (10b) comprising a second scanning device (12b) for scanning a second working beam (50b) over a second working field (40b). At least a movable mirror (12a-2) of the first scanning device (12a) and at least a movable mirror (12b-2) of the second scanning device (12b) are arranged mirror-symmetrically with respect to each other. The first working field (40a) and the second working field (40b) overlap in a common overlap area (42).

Abstract: A method for forming an immersion agent film between the sample holder and the objective of a microscope, comprising an automatic immersion module for supplying immersion agent from an immersion agent reservoir to a target position on the sample holder or on the positioning stage, the automatic immersion module having a spraying device with a nozzle connected to a pump for the purpose of generating an immersion agent jet. A dosed immersion agent jet is sprayed via the automatic immersion module onto a target position on the sample holder or a position on the positioning stage, at a defined speed.

Abstract: Methods and apparatuses for detection of a force acting on an object trapped in optical tweezers and/or for detection of a position change of an object illuminated by a light beam are described. In this respect, light scattered from the object is guided via a telescope arrangement to a detector such that a diverging beam falls onto the detector.
