A protective cartridge for a glare protection apparatus, includes an optical glare protection filter which, in particular, has at least one liquid crystal cell, including at least an open-loop and/or closed-loop control unit, which is configured to control and/or regulate a permeability of the optical glare protection filter, at least between at least one bright level and at least one dark level, depending on a captured work state, on an electronic signal of an external signal source and/or on light irradiation. The permeability of the optical glare protection filter at at least one bright level corresponds to a protection level of less than 2.5, preferably of at most 2.4, advantageously of at most 2.25, particularly advantageously of at most 2 and preferably of at most 1.7.

A test apparatus for electro-optical printed circuit boards having optical waveguides comprises a control device, a beamer and a camera, which can be positioned in such a way that light emitted by the beamer can be coupled by means of a first deflecting element to optical waveguides of the circuit board and can be coupled out by means of a second deflecting element into the field of vision of the camera. The beamer is used in a first phase to determine the position for each deflecting mirror of the first deflecting element which a light spot needs to assume in the image projected by the beamer so that the light spot illuminates the deflecting mirror. The beamer is used in a second phase to illuminate at least one deflecting mirror and to carry out the testing of the optical waveguide associated with the at least one deflecting mirror.
