Angular Measurement Systems OptiAngle Based around a visual autocollimator fitted with a CCD camera the system measures the displacement of a projected graticule from reflective surfaces. The displacement indicates the wedge, prism angle or tilt of a mirror or centration error of a lens system. If used in conjunction with a collimator the deviation angle through a wedge or prism, centration error of a lens or alignment of optical components in a system can be evaluated.

This compatibility leads to an enhanced measuring range and accuracy.
