DEFINITION

Classification: 422/82.05

Measuring optical property by using ultraviolet, infrared, or visible light:

(under subclass 68.1) Apparatus having means for detecting an optical property of the material to be analyzed.

(1) Note. Included in this subclass are apparatus which include some sort of referencing scale with which the sample can be compared by the human eye; e.g., graduations on a pipette, a burette, or a color chart.

SEE OR SEARCH THIS CLASS, SUBCLASS:

55+, for structured visual or optical indicators, per se, in the absence of a positive claimed recitation of an indicator with a referencing scale, even though the indicator could be used with a referencing scale.
