Abstract
Official abstract text for this publication.
A monolithic optical mount having a bore for accommodating an optical element, the bore including: a first ridge located at a first position on the inside circumference of the bore; a second ridge located at a second position on the inside circumference of the bore; and a flexure extending from along the inside circumference of the bore to a point beyond a threaded hole which passes through from the outside circumference of the bore to the inside circumference of the bore; wherein the flexure is actuated by turning a screw in the threaded hole thereby adjusting an amount of force pushing against a point on the flexure by a tip of the screw.
First claim
Opening claim text (preview).
What is claimed is: 1 . A monolithic optical mount having a bore for accommodating an optical element, the bore comprising: a first ridge located at a first position on the inside circumference of the bore; a second ridge located at a second position on the inside circumference of the bore; and a flexure extending from along the inside circumference of the bore to a point beyond a threaded hole which passes through from the outside circumference of the bore to the inside circumference of the bore; wherein the flexure is actuated by turning a screw in the threaded hole thereby adjusting an amount of force pushing against a point on the flexure by a tip of the screw. 2 . The optical mount of claim 1 , wherein the flexure is configured to have a portion of the flexure to flex compliantly so as to conform to an edge profile of the optical element. 3 . The optical mount of claim 1 , wherein a portion of the flexure is progressively increasing in thickness. 4 . The optical mount of claim 1 , wherein the flexure comprises a third ridge at an offset distance from the threaded hole. 5 . The optical mount of claim 4 , wherein the first, second and third ridges are spaced from each other by 120 degrees. 6 . The optical mount of claim 5 , wherein the first, second and third ridges are surface finished based on a surface finish of an edge of the optical element in order to maximize a friction between the ridges and the edge of the optical element. 7 . The optical mount of claim 1 , wherein the mount is calibrated to provide a known clamping force on the optical element for a given torque on the screw. 8 . The optical mount of claim 1 , wherein the mount is calibrated to provide a known wavefront distortion to the optical element for a given torque on the screw.
