neutral density wedge

A strip or annulus of glass coated with a semitransparent material such as inconel. The coating thickness, and as a result its transmission, varies linearly as a function of distance. The neutral density wedge can be found in systems such as laser scanners in which the function of the wedge is to weaken and moderate the light beam in the scanner.
