Definitions
- the invention relates to a microscope system for examining a sample, comprising a microscope with a movable microscope stage on which the sample to be examined can be positioned, and a controller which is designed to transmit a first position signal to the microscope stage, on the basis of which the microscope stage in a first table position can be moved to cause the microscope to examine a first region of the sample assigned to the first table position in a first examination step when the microscope table has moved into the first table position to transmit at least one second position signal to the microscope table, based on the latter the microscope table can be moved into a second table position, and to cause the microscope to examine a second region of the sample assigned to the second table position in a second examination step following the first examination step when the microscope table is in the second e table position has moved.
- the invention further relates to a method for examining a sample by means of a microscope.
- a position signal is transmitted to the microscope stage in a first step.
- the microscope stage is moved into the desired table position on the basis of the position signal.
- a sample area assigned to the table position is examined.
- the microscope system according to the invention for examining a sample comprises a microscope with a movable microscope stage on which the sample to be examined can be positioned, and a controller.
- the controller is designed to transmit a first position signal to the microscope table, by means of which the microscope table can be moved into a first table position; to cause the microscope, in a first examination step, to examine a first region of the sample assigned to the first table position when the microscope table has moved into the first table position; to transmit at least a second position signal to the microscope table, by means of which the microscope table can be moved into a second table position; and to cause the microscope to examine a second region of the sample assigned to the second table position in a second examination step following the first examination step when the microscope table has moved into the second table position.
- the controller is also designed to transmit the second position signal to the microscope stage while the microscope stage is being moved into the first stage position.
- the sample areas to be examined are not yet finally determined at the beginning of the experiment.
- the period of time required to move the microscope stage into the first stage position is used to send the second position signal to the microscope stage.
- the microscope stage can be used immediately, ie without any Delay can be moved to the second table position as soon as the first examination step is completed. This means that no time is lost for the transmission of the position signals, and the time saved can be used for the actual experiment.
- the microscope system according to the invention thus enables a flexible adaptation of the sample areas to be examined in the course of the experiment, a faster light microscopic examination than before.
- the respective position signal which the control transmits to the microscope stage at a given point in time and on the basis of which the microscope stage can be moved into the associated stage position at a later point in time
- a control signal or trigger signal which the desired Table positioning actually triggers by moving the microscope table at the aforementioned later point in time.
- Another advantage of the microscope system according to the invention is that the microscope stage and / or the controller that controls the microscope operation only has to provide a small number of position signals in order to move the microscope stage in the desired manner. Powerful storage elements can therefore be dispensed with in the microscope components mentioned.
- a further position signal is transmitted to the microscope table by the control unit, while the microscope table is moved into a table position which is assigned to a position signal preceding this further position signal.
- the microscope stage is then moved into a stage position based on the further position signal, which in turn is assigned a further sample area.
- This further sample area is then examined by means of the microscope in a further examination step following the second examination step. The aforementioned Steps are repeated until all desired sample areas have been microscopically examined.
- the control of the microscope system is preferably designed to generate a third position signal as a function of an examination result detected by the microscope in the first examination step and to transmit this third position signal to the microscope stage while the microscope stage is being moved into the second stage position, and that To cause the microscope to examine a third area of the sample assigned to the third table position in a third examination step following the second examination step when the microscope table has moved into the third table position.
- This particularly advantageous development enables the experiment to be flexibly adapted to the results of the examination carried out so far with regard to the selection of the table positions to be approached by the microscope table and thus the sample areas to be examined which are assigned to these table positions.
- the microscope stage can be moved in a plane perpendicular to the optical axis of an objective of the microscope. As a result, as many areas of the sample as possible can be examined. Alternatively, the microscope stage can only be moved along a direction perpendicular to the optical axis of the objective of the microscope.
- the microscope comprises a detector which is designed to send examination results determined in the first examination step and / or in the second examination step to the controller. A selection of further sample areas to be examined can be made on the basis of these examination results.
- the microscope table preferably has a table drive and a table control unit which is designed to receive the respective position signal transmitted by the control and to control the table drive on the basis of the received position signal for moving the microscope table.
- a distinction must be made here between the position signal that represents the table position to be set and the control signal or trigger signal that triggers the actual adjustment of the microscope table.
- the stage control unit sends such a trigger signal to the stage drive in order to cause the stage drive to move the microscope stage into the desired stage position.
- the table drive is designed, for example, as an electric motor and enables the micros to be moved copically depending on the position signals provided.
- the microscope stage preferably has a memory in which the respective position signal can be stored.
- the aforementioned memory is preferably part of the table control.
- the control of the microscope system can also have a memory for the position signals.
- the microscope can in particular be a transmitted light microscope or an incident light microscope.
- the microscope can also be designed both as an upright microscope and as an inverted microscope.
- the invention further relates to a method for examining a sample using a microscope, comprising the following steps: positioning the sample to be examined on a movable microscope stage of the microscope; Transmitting a first position signal to the microscope stage; Moving the microscope table into a first table position based on the first position signal; Get the microscope into one first examination step to examine a first region of the sample assigned to the first table position; Transmitting at least a second position signal to the microscope stage; Method of the microscope table based on the second position signal in a second table position; and causing the microscope to examine a second region of the sample assigned to the second position of the microscope stage in a second examination step following the first examination step. It is further provided that the second position signal is transmitted to the microscope stage while the microscope stage is being moved into the first stage position.

- the main control unit 104 transmits a third position signal to the Table control unit 130, which stores the third position signal in its internal memory 131.
- a fifth step S5 the detector 122 records an image of a second region of the sample 118 of the sample assigned to the second table position, which in turn is then transmitted to the main control unit 104 and processed there.
- a further position signal is transmitted by the main control unit 104 to the table control unit 130 and stored there, while the microscope stage 116 is moved into a position which is assigned to a position signal preceding the respective further position signal.
- the microscope stage 116 is moved into a further stage position on the basis of a trigger signal, to which another region of the sample to be examined is assigned. This further area is then examined with the detector 122 by way of imaging before a position signal is again transmitted by the main control unit 104. This is repeated until the examination of sample 118 is complete.
- a position signal is transmitted to the microscope stage in a first step.
- the microscope stage is then moved into a stage position that corresponds to the previously transmitted position signal.

- step S21 to S23 the microscope table is already supplied with all table positions one after the other in the form of corresponding position signals which are later to be approached by the microscope table.
- step S24 the microscope stage is then moved into a first stage position which corresponds to the first of the previously transmitted stage positions.
- step S25 a first sample area assigned to the first table position is examined. Steps S24 and S25 are then carried out successively for all further table positions that have been transmitted in the start phase.
- the method of sequential reloading according to FIG. 4 has the disadvantage of stretching the experiment as it were over time.
- the precharging method according to FIG. 5 has the disadvantage of the delayed start of the experiment.
- the preloading does not allow any adjustment to the table positions to be used in the experiment.
- the available memory size of the table control unit 130 limits the experiment size, i.e. for example the total number of table positions that can be approached in the course of the experiment.
- the invention provides a solution that enables both a particularly rapid sample examination and a flexible adaptation of the sample areas to be examined during the experiment and does not represent any limitation in the size of the experiment.
