Abstract
A filter changer for a radiation transmitter comprises a filter which is adjusted between a first position out of the beam path of the radiation transmitter to a second position in the beam path. The changer includes guides for guiding the filter for movement along a linear path, an arm having one end engaging the filter and the other end engaging an actuating arrangement so that when the arm is rotated against a spring, the filter is moved from the first to the second position and when the arm is released from the actuating arrangement, the spring biases the arm and filter back into the first position.
