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.

Köhler Illumination

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.
