ABSTRACT:
An arrangement for rotatable adjustment of a cap on an eyepiece housing with a stationary pin pointing radially outward from the eyepiece housing and a groove which is assigned to the pin, arranged on the inner side of the cap and rises in the axial direction, is characterized in that, in a plane at right angles to the longitudinal axis of the eyepiece housing, three pins are arranged on the latter, the heads of which pins have at least approximately the same spacing from the longitudinal axis, and in that the sliding bottom of the groove assigned to each pin has a smaller spacing in relation thereto, so that the cap bears against the pins under prestress.
