DEFINITION

Classification: 356/332

Having adjustable color or bandwidth:

(under subclass 331) Subject matter including structure to vary the bandwidth or to vary the average or median frequency of the band over the range of the light emitted from the monochromator.

(1) Note. The variation may be obtained by changing the width of one of the slits or by changing the reflection angle of the dispersing element.
