Multi-state marker /manipulator for optical systems which track the location of the object is characterized by the fact that it consists of five spheres [1], and two spheres are interchangeably covered and three are always visible; spheres are mounted on pins [4] connected by arms [3]; has at least two screening mechanism [5], mounted on pins [4] where screening mechanism [5] consist of two hemispheres [6] mounted on sleeve [7] equipped with a pull-off spring that pulls it towards the sphere [1]; the pull arms [8], which perform the opening of the hemisphere [6], which simultaneously deflect the hemisphere [6], are connected by the connector [10]. The connector has a hinge [11]. The control is carried out by an additional handle [12]. Spheres [1] are covered with reflective material and the tracking system is a camera.
