Class Information
Number: 356/402
Name: Optics: measuring and testing > By shade or color
Description: Subject matter wherein light (emanating directly from a light source, or transmitted through or reflected from a substance) is analyzed for its frequency content by dividing the light into its component frequencies or bands of frequencies (which are usually of as predetermined character), or by comparison in frequency or intensity with standard lights (emanating directly from a light source, or transmitted through or reflected from a substance).
