DEFINITION

Classification: 396/119

Photoelements with different optical path lengths:

(under subclass 111) Subject matter wherein the photoelement system includes photoelements located at different distances from the exposure objective.

(1) Note. The different distances may be the result of a light-modifying element that changes the distance the light travels (i.e., optical distance) which may be different than the distance measured by a ruler (i.e., physical distance).
