- Corresponding positions include, in particular, different positions in the plane of a microscope table, also referred to as x / y positions, which can be approached in automated microscopes by a corresponding motorized adjustment of a cross table, also referred to as x / y table, but also different distances of the objective to the object, also referred to as y-positions, which can be set in such automated microscopes by a corresponding motorized adjustment of a focus drive.
- corresponding different positions can also be set manually in addition to an automated setting within the framework of a so-called sequence control. As is customary in the professional world and, for example, also by F.
- a “process control” is defined as a control system with an inevitably step-by-step process understood, in which the step from one step to the next according to the program takes place depending on the step conditions.
- the steps typically correspond to successive states of the device to be controlled, in the present case successive settings of an automated microscope.
- the switching conditions can be specified by the device to be controlled, in which case one also speaks of a process-controlled sequence control. In the present case, it is possible, for example, to move on to the next step when a certain object area has been recorded or in a certain focal position.
- time-controlled sequence control the transition conditions are solely dependent on the time. Mixed forms are also possible.
- object should be understood here broadly and refer to any object which can be introduced into a microscope and examined there and which can be prepared for microscopy in any way.
- object can be biological objects in the form of cuts or smears, but also non-biological natural objects such as rocks or minerals and artificially produced objects such as wafers.
- the present invention is basically suitable for all areas of microscopy that can be carried out, for example, in incident light, transmitted light, with illumination and / or detection in the visible wavelength range and / or with fluorescence illumination and / or fluorescence detection as well as in wide field or scanning.
- a method is proposed in which, when it is determined when querying the hardware for recognizing device components that these device components have not been clearly identified or excluded, the microscope user is asked for corresponding information by using the information provided in Possible alternatives to the device components are listed in a dialog window in the microscope control software, for example, and the microscope user can then decide which alternatives are applicable. After a decision by the microscope user, some of the alternatives can either be excluded or new device components can be added to the list of the remaining components, so that a new, complete device configuration is created for the microscope to be controlled after the configuration files have been run through.
- EP 1 697 782 A1 also describes a device and a method for configuring a microscope.
- the invention there is based on the object of creating a device for teaching-in and configuring individual components of an at least partially automated microscope.

- corresponding configuration settings are made for a user via a user interface before a corresponding experiment is carried out with the microscope.
- wavelengths or wavelength ranges can be set as a function of an examination method to be carried out.
- a corresponding automatic optimization can also be carried out here.
- DE 103 61 158 B4 discloses a microscope in which several assemblies can be configured using a user interface.
- DE 39 33 064 C2 discloses a method in which user-specific and sample-specific presettings of a microscope can be made by means of a control device.

- an area in x and y and / or z Define direction in which the sample is scanned during image acquisition, fixed exposure times and / or a laser or LED intensity for different acquisition channels.
- a recording program is set according to step a).
- a parameter to be monitored is specified or selected.
- conditions with regard to the parameter and actions can also be specified as a function of the fulfillment of the conditions.
- a sequence control is defined on this basis.

In this way, the sequence, which is still completely predetermined in a conventional manner, can be expanded to include appropriate conditions.
- the object of the present invention is to make the configuration of a sequence control of an automated microscope simpler and more user-friendly and in this way to create an improved automated microscope system.

If it is said here that the user "brings" the corresponding microscope components, this can be done either by direct action (for example by manual adjustment on the respective component) or indirect action (for example via an adjustment mechanism or by means of control signals on motors).
- the examination step or steps that can be carried out using the same or any other microscope components in any combination are, for example, examination steps that involve certain lighting methods (transmitted light, incident light, fluorescent lighting, bright field lighting, dark field lighting, phase contrast lighting, etc.) and lighting intensities (e.g. an examination with lower and higher lighting one after the other), lighting pattern (e.g. examination with Fluorescent light, then light in the visible, then by means of a certain lighting method, or for example in the form of a scanning scan such as a spiral scan).

- the steps correspond to successive settings of the microscope according to the respective setting data records.
- the switching conditions can be specified as part of a process-controlled sequence control, for example on the basis of detected sample properties or a return value, after which a previous step is ended.
- the switching conditions can be specified solely on the basis of an elapsed time.

- the image data obtained and stored in the one or more acquisition steps are advantageously subjected to an image analysis in one or more evaluation steps, which in particular also works with information relating to the positions and / or the examination steps carried out. In this way, a targeted evaluation corresponding to the examination method can be carried out largely automatically in the sequence control.
