Abstract
An optical system for exciting and measuring fluorescence of samples has a first laser; a deflection element; a mirror; and an optic fixed in relation to one another. A unit is linearly movable back and forth along the optical axis and is mechanically connected to an oscillating linear drive. The optic acts as a collimator and the mirror acts to deflect the collimated light diametrically opposite to the bundled light of the laser. A table for receiving sample holders for samples; an optical arrangement for imaging a second focal point; an aperture plate in the second focal point; a first spectral filter; and a first detector are parts of the optical system and a focusing beam of the light emitted by the laser and is deflected by the deflection element toward the mirror.
