Abstract
An adjustable pinhole, in particular for a beam path for illumination and/or detection in a laser-scanning microscope. The pinhole consists of at least two planar basic modules, which have frame-like joints, on which at least one blade is arranged in a displaceable manner in one direction, whereby the basic component advantageously contains at least one integrated, preferably optical or electromagnetic actuator. A device is provided at the blade, or connected with it, for preferably optical or electromagnetic detection of the position, and is provided, advantageously, with two asymmetric apertures, with mutually opposite orientation, for optical detection of the position, whereby in front of or behind the apertures, a slit is provided, oriented preferably at a right angle to the direction of displacement, and the quantity of light passing through the slit is detected separately for each aperture.
