Universal device for the relative displacement between the optical plane and the focal plane of a lens and a camera

摘要

The invention relates to a device which consists of a frame (1) for attaching the body of the camera (2), from the sides of which emerge two forks (5) that end in respective joints (6) for a bridge (7-7'), having an upside-down "U" configuration, so that the imaginary axis that connects the two joints coincides with the focal plane or sensor of the camera (2). The joints (6) include means for adjusting the inclination of the bridge (7-7'), as well as guiding means (9) for axial movement of the side arms (7') of the bridge, while the longitudinal member (7) has longitudinal guiding means (11) for a carriage (12) which is associated at the bottom with a rotary base (14), the axis of rotation of which coincides with the focal plane or sensor of the camera (2). The rotary base (14) has guiding means for a support (17) to which the lens (18) is attached.
