Abstract: A low-drift optical mount comprising a first plate, a second plate, at least one drive rod, at least one collet. A first collet may extend through a bore of the second plate and has an inner screw matching the external screw of a first drive rod. The first drive rod may have a contact end with the first plate and a spring pulls the first plate back toward the second plate. The collet may have at least one slot that extends through the own inner thread surface. The slot can relieve the drift performance induced by grease which fills in the thread fit clearance and further improve the position stability of optical mount.
