1. An slit lamp comprising:

  • a laser being provided as an illumination source; and

    one reflection element that, during use of the illumination unit, is controllable by a drive voltage in a defined manner for the deliberate deflection of the laser beam and is tiltable about two axes independent from one another;

    wherein the one reflection element is controlled such that an amplitude of an oscillation of the one reflection element is proportional to the drive voltage, and the deliberate deflection generates optical sectional images in transparent media; and

    wherein each of the two independent axes, about which the reflection element is tiltable, is arranged to always intersect both with an upstream beam path and with a downstream beam path of the laser beam which is deflected by the reflection element.
