The present invention relates to an instrument and method of aligning a collimator. The instrument includes a frame base, a clamp, a first axis stage, a second axis stage, and a rack. A ferrule grasping a fiber therein is inserted in a glass tube, and the glass tube is secured to the frame base by the clamp. A pinion is fixedly mounted on one end of a GRIN lens, which is inserted in the glass tube, and engaged with the rack. The first axis stage moves the GRIN lens along the cylindrical axis of the glass tube, and the second axis stage rotates the GRIN lens around the cylindrical axis of the glass tube. When a light beam emitted from the collimator reaches the maximum intensity, the instrument of the invention accomplishes the alignment of the collimator.

Instrument and method for aligning optical collimators

A method is designed to adjust the distance between the central axes of two ocular lenses of an optical instrument. The method involves the use of a link mechanism to actuate two movable prisms and the two ocular lenses of the optical instrument to move respectively along a base surface such that the optical axes of effective diameters of the two movable prisms are coaxial with the optical axes of the corresponding ocular lenses.
