MEASUREMENT OF INTENSITY, VELOCITY, SPECTRAL CONTENT, POLARISATION, PHASE OR PULSE CHARACTERISTICS OF INFRARED, VISIBLE OR ULTRAVIOLET LIGHT

**Definition:** This place covers:

Apparatus or methods for measuring properties of infrared, visible, or ultraviolet light, for the purpose of:

**Limiting references (this place does not cover):** - Non-optical measurement of temperature -> G01K - Gas analyzers -> G01N21/00 - Ellipsometry -> G01N21/00 - Sample holders or sample preparations leading to an enhanced detection, e.g. SERS substrates -> G01N21/00 - Stabilization of the wavelength of a laser by means of a feedback loop, without numerical determination of said wavelength -> H01S5/0687

**Glossary:** - Optical: concerning light with wavelengths in the infrared, visible and ultraviolet domains - UV: Ultraviolet - Vis: Visible - NIR: Near Infrared
