Christoph Cremer

Christoph Cremer (born in Freiburg im Breisgau, Germany) is a German physicist and professor at the Ruprecht-Karls-University Heidelberg, honorary professor at the University of Mainz and group leader at the Institute of Molecular Biology (IMB) a newly established research centre on the campus of the Johannes Gutenberg University of Mainz, Germany, who has successfully overcome the conventional limit of resolution that applies to light based investigations (the Abbe limit) by a range of different methods (1971/1978 development of the concept of 4Pi-microscopy; 1996 localization microscopy SPDM; 1997 spatially structured illumination SMI).

Confocal microscopy

Confocal microscopy, most frequently confocal laser scanning microscopy (CLSM) or laser confocal scanning microscopy (LCSM), is an optical imaging technique for increasing optical resolution and contrast of a micrograph by means of using a spatial pinhole to block out-of-focus light in image formation.

Dichroic filter

A dichroic filter, thin-film filter, or interference filter is a very accurate color filter used to selectively pass light of a small range of colors while reflecting other colors.

Multifocal plane microscopy

Multifocal plane microscopy (MUM) or Multiplane microscopy or Biplane microscopy is a form of light microscopy that allows the tracking of the 3D dynamics in live cells at high temporal and spatial resolution by simultaneously imaging different focal planes within the specimen.

Objective (optics)

In optical engineering, the objective is the optical element that gathers light from the object being observed and focuses the light rays to produce a real image.

Optical axis

An optical axis is a line along which there is some degree of rotational symmetry in an optical system such as a camera lens or microscope.

Optical path length

In optics, optical path length (OPL) or optical distance is the product of the geometric length of the path light follows through the system, and the index of refraction of the medium through which it propagates(OP.
