to carry out bright field recording dark field illumination differential interference contrast and segmented illumination the first frequency for image recording can be in particular a multiple of the second frequency the second frequency for example can be at least 24 or 25 or 30 hz and the first frequency can therefore be at least 48 50 60 hz it can also be for example 100 150 or 300 hz the construction of the microscope described here in connection with fig1 is to be understood to be purely an example the configuration according to the invention using the digital evaluation unit 7 can be realized in any known microscope type the microscope 1 described here is preferably configured for material analysis in the microscope according to the invention furthermore a greater region can be recorded using the image sensor 9 than the region of the recording that will then be used to generate the output images those parts of the recording not represented in the output image can be used for other functions of the microscope for example for automatic focusing and or automatic image stabilization although some of various drawings illustrate a number of logical stages in a particular order stages which are not order dependent can be reordered and other stages can be combined or broken out alternative orderings and groupings whether described above or not can be appropriate or obvious to those of ordinary skill in the art of computer science moreover it should be recognized that the stages could be implemented in hardware firmware software or any combination.
