摘要: Modular illumination system for transmitted-light microscopes, embodying the Koehler illumination principle, and usable on microscopes of short or long optical transmission length, including a telecentering lens disposed in the light beam path defined according to Koehler between the luminous field diaphragm and the aperture diaphragm and imaging the luminous field diaphragm at infinity the telecentering lens is displaceable, preferably perpendicularly to the optical axis.

摘要: An achromatic phase retarder comprises at least one prismatic body with two total reflection surfaces. The light entry surface forms an angle of incidence .alpha., which is different from 90.degree., with the direction of incidence of a light beam, and a first total reflection surface forms a defined angle .phi. with the light entry surface.
