摘要:
The invention relates to a device for optical excitation, in particular luminescent excitation of biomolecules (40) in a fluid sample, comprising a multiple wavelength generator which generates at least one array of spots (60) with different wavelengths at least one defined area of the device.
摘要:
Particles emitted by a radiation source, and moving from the radiation source towards a processing system for processing the radiation from the radiation source, are filtered out of radiation propagating through a predetermined cross section of the radiation as emitted by the radiation source by a filter system. The filter system includes a plurality of foils and a transporter for transporting the foils along a trajectory which extends within the beam so that the foils intercept the particles within the beam. The transporter is arranged to transport the foils by a substantially translatory movement of the foils along at least a part of the trajectory.
