Definitions
- the invention relates to a method for operating an optical system and an optical system.
- Optical systems for example stereomicroscopes, are used in a wide variety of applications to generate a spatial image of an examination object.
- such optical systems are used in medical surgical microscopes to view an operating area.
- the spatial image of the examination object is generated using the stereomicroscope, which is a representative of the device class of reflected light microscopes.
- the examination object is illuminated from the outside.
- Two separate beam paths are usually formed, which in turn are each equipped with an associated lens system.
- the optical axes of the two beam paths run through a converging lens arrangement upstream of the lens systems in the direction of the examination object.
- Both the lens systems and the converging lens arrangement can comprise a plurality of optical lenses.
- the various optical lenses are used to set a focus and a zoom factor of the stereomicroscope. For this purpose, the lenses are moved individually or in groups along the respectively assigned optical axis.
- the shifting of optical elements for focus adjustment or for setting the zoom factor can be carried out with the aid of motor-driven adjustment devices which shift the optical element into a desired position along the optical axis.
- motor-driven adjusting devices are provided with an actuating means, for example one that controls the voltage or Power supply control, operated by the user. As long as the user switches on the actuating means, the lens moves along the optical axis. The user stops this movement by switching off the actuating means.
- Document DE 103 23 629 A1 describes a traveling field linear motor with which optical elements, for example an optical lens, arranged in a sleeve can be displaced along the optical axis. This is achieved by means of a magnetic traveling field moving along the optical axis. The magnetic traveling field and thus also the shift positions of the optical elements can be adjusted very finely.
- the well-known Wanderfeld linear motor supports the miniaturization of optical systems.
- the object of the invention is to provide a method for operating an optical system with a microscope and an optical system in which the user-friendliness is improved, in particular with regard to simple operation and targeted positioning of the optical elements within an optical channel.
- This object is achieved according to the invention by a method for operating an optical system with a microscope according to independent claim 1 and an optical system with a microscope according to independent claim 11.
- the invention encompasses the idea of operating an optical system in such a way that, in response to a user input for changing a focus setting and / or a zoom factor of the microscope, a desired focus setting and / or a desired zoom factor is automatically generated with the aid of motor-driven adjustment devices are generated by, in response to the detected user input in a control device, control signals corresponding to stored default settings and converted into movements of the optical elements of the microscope with the aid of the respective motor-driven adjusting devices.
- the stored default settings include electronic information about positions of optical elements, in particular lenses, of the microscope for certain focus settings and / or zoom factors.
- the microscope can be automatically adjusted, depending on the detected user input, using the stored default settings so that a specific focus setting and / or a specific zoom factor is given.
- the default settings have been determined in advance for the optical system, for example using measurements on an optical bench, and stored in the form of electronic data.
- the user does not have to independently move the optical elements along the optical axis and search for an optimal positioning, as is provided in the prior art. Rather, the user merely specifies a desired focus setting and / or a desired zoom factor, whereupon the optical system automatically makes a focus / zoom factor setting taking into account the stored default settings. There is also no need to shift the lenses by hand.
- An expedient embodiment of the invention provides that a coarse focus adjustment is carried out when adjusting the focus setting, in that coarse control signals comprised by the control signals are generated in the control device and transmitted from the control device to the motor-driven adjusting device of the converging lens arrangement and the converging lens arrangement with the aid of the motor-driven Adjustment device of the converging lens arrangement is shifted according to the coarse control signals.
- coarse control signals comprised by the control signals are generated in the control device and transmitted from the control device to the motor-driven adjusting device of the converging lens arrangement and the converging lens arrangement with the aid of the motor-driven Adjustment device of the converging lens arrangement is shifted according to the coarse control signals.
- a fine focus setting is carried out by generating fine control signals comprised by the control signals in the control device and by the control device to the respective motor-driven adjustment device of the first lens arrangement in one or all beam paths are transmitted and the first lens arrangement is shifted in one or all beam paths with the aid of the respective motor-driven adjusting device in accordance with the fine control signals.
- the setting of the zoom factor is carried out by comprising the control signals
- Zoom control signals are generated in the control device and are transmitted from the control device to the respective motor-driven adjusting device of the second lens arrangement in one or all beam paths and the second lens arrangement is shifted in one or all beam paths with the aid of the respective motor-driven adjusting device in accordance with the zoom control signals.
- the scope of the electronic information to be stored for the preset data is minimized in that when the control signals for setting the focus setting and / or the zoom factor are generated in the control device, an interpolation between selected preset data of the stored ones Preset data is executed. Interpolation can also be used to carry out focus settings and / or settings of zoom factors for which the associated positioning of the lenses has not been measured in advance. A linear interpolation between the preset data used is usually carried out.
- the converging lens arrangement, the first lens arrangement and / or the second lens arrangement are displaced linearly during the displacement according to the control signals with the aid of the respective motor-driven adjusting device.
- a linear motor is preferably acted upon by the control signals to carry out the displacement.
- the examination object is spatially mapped onto several electronic storage media, each of which is assigned to a beam path.
- the optical beam paths can of course be made available directly to the viewer's eyes via so-called tubes.
- a preferred development of the invention provides that a respective zoom factor is set in the beam paths by the first lens arrangement, the second lens arrangement and / or the converging lens arrangement being displaced with the aid of the respective motor-driven adjustment device (s), whereby differentiate the zoom factors of the beam paths that can be set. In this way it is possible to generate an enlarged display of one of the channels on a monitor or a camera, whereas the other channel has a lower magnification, for example for the visual observation of the operator when the optical system is designed as a stereo microscope.
- the optical system preferably comprises a stereomicroscope.
- Motor-driven adjustment devices using a moving magnetic traveling field as described for example in document DE 103 23 629 A1, have proven to be particularly advantageous for an exact and finely graduated displacement of lenses in the microscope.
