Abstract
Divider for directing an X-ray light beam into two or three directions, which beam emerges from the screen of an X-ray image intensifier in diagnostic X-ray arrangements. The divider is disposed at 45.degree. with respect to the optical axis, and consists essentially of a slit mirror which has a non-transparent metallization with one or two non-metallized, transparent areas or gaps therein, these areas corresponding to the required divisional ratios, there being similarly non-transparent mirrors or reflecting prisms behind the gaps.
