METHOD FOR DISPLAYING RESULT OF MEASUREMENT OF ECCENTRICITY
First Claim
Patent Images
1. A method for displaying a result of measurement of eccentricity, the method comprising the steps of:
- sequentially projecting an indicator to a position of each design apparent center of curvature of a plurality of surfaces to be measured, the surfaces being included in a lens system to be measured; and
displaying an amount of eccentricity of each surface to be measured, the amount of eccentricity being determined from a state of a reflected image of the indicator, the reflected image being reflected from each surface to be measured,wherein the amount of eccentricity is magnified using a magnification factor and the magnified amount of eccentricity is represented in a sectional view of the lens system, using a scaling factor of the lens system to display the lens system, wherein the scaling factor and the magnification factor are independently valued.

Abstract
A method for displaying a result of measurement of eccentricity in an optical system is provided where an amount of eccentricity for each lens element'"'"'s surface in a lens system can be displayed and where the amount of eccentricity displayed can be a magnified amount of eccentricity. Additionally a sectional view of the lens system can be displayed using scaling factor.
