ABSTRACT:
An adjustable holder has a base, a cover and a sphere-like element for supporting a prism or other optical element within a central cavity formed in the base. The base and cover have interior spherical surface portions which are engaged by exterior spherical surface portions on the prism-supporting element so as to allow universal movement of the prism relative to the base for readjusting the angular position of the prism relative thereto in roll, pitch and yaw simultaneously. The cover may be tightened onto the base for clamping the sphere-like element therebetween and holding the prism in the desired adjusted position.
