Abstract
A device for measuring the oscillation amplitude of the tip of a capillary by means of a light beam comprises a light source and an opto-receiver and two apertured diaphragms that are arranged between the light source and the opto-receiver and which lie on a common axis. The apertured diaphragms are preferably formed by means of drill holes arranged on a common axis in side walls of a channel formed in a body. The two apertured diaphragms define the diameter of the light beam.
