  • Method and apparatus useful for determining an angle between a virtual optical axis and a planar surface
    Patent number: 5207000
    Abstract: A line is extended along a virtual optical axis of an objective lens. The line extends between a transparent plate, which is attached to the lens, and another transparent plate which is secured to a planar surface. The objective lens is part of an optical measuring instrument. An angle indicator is secured to the planar surface. The angle indicator is rotatable so that where the line touches the angle indicator, the angle between the planar surface and the virtual optical axis may be read with respect to azimuth and elevation.
