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.

Basic Microscopy

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.

Achieving High-Quality Images

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.

Basic Staining Methods in Laboratory Routine

Most of the cells and microorganisms you are observing with your light microscope are poor of color and contrast. To enhance the contrast and color of interesting features you can apply different stains (dyes).
