Centering Steep Aspheric Surfaces

Centering, PSM Applications, Published Papers

1. INTRODUCTION Finding the optical axis of an aspheric surface is an essential part of making an aspheric lens because the center of curvature, or optical axis, of the second side must lie on, or be coincident with, respectively, the optical axis of the first side for maximum optical performance. Looking at the center of […]

Practical Alignment Using An Autostigmatic Microscope

Centering, Published Papers

ABSTRACT Auto-stigmatic microscopes (ASM) are useful for bringing centers of curvatures of lenses and mirrors to the centers of balls used as part of an alignment fixture. However, setting up the fixture to get the balls used for alignment in a straight line to represent the optical axis generally requires another piece of equipment. We […]

Lens Centering Using The Point Source Microscope

Centering, Published Papers

ABSTRACT Precision lens centering is necessary to obtain the maximum performance from a centered lens system. A technique to achieve precision centering is presented that incorporates the simultaneous viewing through the upper lens surface of the centers of curvature of each element as it is assembled in a lens barrel. This permits the alignment of […]

Conjugate Selection For Precision Lens Centering

Centering, Published Papers

ABSTRACT The concept of centering a precision, symmetric lens system using a high-quality rotary table and an auto-focusing test instrument are well known. Less well known are methods of finding convenient, or easily accessible, lens conjugates on which to focus while performing the centering operation. We introduce methods of finding suitable conjugates and centering configurations […]

Centering with the PSM

Centering, PSM Applications, Published Papers

Centering with the Point Source Microscope (PSM) is a perfect application. Centering with the Point Source Microscope (PSM) is a perfect application. When a spot of light from the objective focus is reflected back from a concave surface sitting on a rotary table, it will sweep out a circle on the video screen as the […]
