Class Information
Number: 356/432
Name: Optics: measuring and testing > For light transmission or absorption
Description: Subject matter wherein visible radiation is passed directly or with internal reflection through solid, liquid, or gaseous substances or any mixture thereof including coated solids, and detected visually or photoelectrically after it has passed through the substance for the purpose of determining the intensity, the change of intensity, the extinction of the radiation, or the outline of the radiation source or image.
