Abstract: A flow cytometer comprises a flow cell defining a flow channel for flowing a liquid containing a particle through the flow cell, a light source arranged to emit light to the particle flowing through the channel, the light being incident to the particle at an incidence angle inclined to a normal direction with respect to a flow direction of the particle through the channel, and a plurality of light detectors arranged around the flow cell and arranged for receiving light diverging from the particle.

Abstract: The invention relates to a multi-modal imaging system (2) for non-invasive examination of an examination object (10), comprising a multi-photon imaging system for providing high-resolution detailed images of the examination object (10), which imaging system comprises a radiation source (12), the latter generating an excitation beam (21) of near infrared femtosecond laser radiation for triggering secondary radiation emitted by the examination object (10), and a focusing optical unit (30), by means of which the radiation of the radiation source (12) is directable at a measurement position of the examination object (10), wherein the focusing optical unit (30) and a laser head (14) of the radiation source (12) are provided in a measuring head (4), which is pivotable, rotatable and flexibly positionable freely in space such that the examination of the examination object (10) is performable under any desired solid angle, and comprising at least one confocal detection device, which is at least partly integrated in t

Abstract: A nonlinear laser scanning microscope for flexible, noninvasive three-dimensional detection comprising a measuring head which is flexibly connected to at least one radiation source by transmission optics and can be freely positioned in space, at least one controllable tilt mirror is arranged for aligning the excitation beam in order to keep the excitation beam concentric to an aperture-limited optical element of the measuring head, a test beam which is coupled out of the excitation beam onto a spatially resolving photodetector for monitoring the center alignment of the test beam as a conjugate position to the target position of the excitation beam and directional stabilizing the excitation beam by a control unit of the tilt mirror depending on a determined deviation.
