Device for carrying out biochemical fluorescence tests

The invention relates to a device for carrying out biochemical fluorescence tests by means of which the different biochemical interactions can be detected. With the aid of the invention it shall be allowed for a very large number of individual samples to be detected low costly and with a high sensitivity, and in addition it shall be achieved a high spatial resolution. According to the invention this object is solved with a device by means of which linearly polarized light of a laser diode is directed upon a plate-shaped carrier through an optical arrangement comprising at least one polarization beam splitter, a quarter-wave plate and a focussing optical element. In addition to binary, optically detectable information structures a plurality of fluorophore-marked samples is discretely arranged as well on the carrier rotating about an axis. Light reflected on the information structures is directed upon an optical detector by means of the optical arrangement for detecting information, and fluorescent light emitted from the fluorophore-marked samples is directed upon an optical detector for the fluorescent light via a spectral filter separating in a wavelength-selective and spatial manner.
