Abstract
A terminal for a light conductor for uniform illumination of a rectangular field in medical and, especially, dental applications has a transparent, cylindrical lens body in a mount with its axis perpendicular to the axis of a socket for receiving the light exit end of the light conductor. The side of the cylindrical lens body facing the socket has a trough-shaped recess of symmetric cross section. The width of the trough-shaped recess continuously expands from the bottom to the margin of the trough-shaped recess, the bottom being perpendicular to the axis of the socket and perpendicular to the axis of the cylindrical lens body.
