Optoelectronic device for determining relative movements or relative positions of two objects

An optoelectronic device for determining relative movements or relative positions of two objects, comprising:

• a first object fixed relative to a frame of the device;
• a second object mounted in spaced relation to the first object and adapted for movement relative thereto;
• at least one measuring cell for determining movement or displacement of the second object relative to the first object;
• and
• a stop arrangement for limiting the movement or displacement of the second object relative to the first object,
• wherein the stop arrangement comprises a mounting part fixed relative to a frame of the optoelectronic device, and at least one generally elongate stop member arranged laterally of and substantially rigidly connected with the mounting part;
• wherein the mounting part is generally elongate and is fixed relative to the frame of the device at an end region thereof, and
• characterized in that the at least one stop member is substantially rigidly connected with the mounting part at a location spaced from said end region of the mounting part fixed to the frame.
