ABSTRACT:
The invention relates to a method for determining luminescent molecules by means of optical excitation in confocal measurement volumes using a diffractive optical element. The method is particularly suitable for single-molecule determination, e.g. by means of fluorescence correlation spectroscopy or by means of dynamic light scattering. An apparatus suitable for carrying out the method according to the invention is furthermore disclosed.
