Education is a continuous process of facilitating teaching and learning. It is part of every stage in your live such as school, university and apprenticeship.
Teaching is the art of passing knowledge of the few on to the many. For this you need a good overview of all the learners, a deep insight into the individuals, and the option of networking them all together.
Microscopes are an essential part in many curricula. You use them as a tool to train e.g. biology as well as to train the techniques of microscopy. ZEISS systems for classical and digital classrooms make your courses a real success both for you and your students.
- Unlock the full potential of your students in biology courses and medicine classes
- Gain knowledge of sample preparation, staining procedures and sample examination to identity e.g. blood cell disorders
- Connect your microscopes to a digital classroom and produce an engaging atmosphere that motivates students
- Use microscopes to attract visitors in your museum of natural history and zoology, animal parks and zoos
- Profit from continuous learning or a vocational training in histology, cytology, hematology or gynecology
Basic concepts in microscopy
Through various sections, learn more about the principles of microscopy and get detailed advice and comments on how to use the different methods with your microscope. For instance, start with the concepts of image formation, numerical aperture and the Köhler illumination.
How the Microscope Forms Images
Optical microscopes belong to a class of instruments that are said to be diffraction limited, meaning that resolution is determined in part by the number of diffraction orders created by the specimen that can be successfully captured by the objective and imaged by the optical system.
Illumination of the specimen is the most important variable in achieving high-quality images in microscopy and critical photomicrography. Köhler illumination was first introduced in 1893 by August Köhler of the Carl Zeiss corporation as a method of providing the optimum specimen illumination.
Numerical Aperture and Resolution
The numerical aperture of a microscope objective is the measure of its ability to gather light and to resolve fine specimen detail while working at a fixed object (or specimen) distance. Resolution is determined by the number of diffracted wavefront orders captured by the objective.
