DEFINITION

Classification: 359/694

Adjusting mechanism:

(under subclass 676) Subject matter comprising structure for changing the axial spacing between components of the lens.

(1) Note. This subclass provides for the mechanical adjusting structure. Where the optical relationship is set forth in the claims, classification is in subclasses 676-693.

SEE OR SEARCH THIS CLASS, SUBCLASS:

823+, for mechanisms that axially shift the lens components to axially adjust the focal plane of the lens.
