Photometry is the science that studies light radiation as it is perceived by human vision. 

Spectrometry is the experimental study of the spectrum of a physical phenomenon, i.e. its decomposition on an energy scale: frequency, wavelength, etc. Today, this principle is available in a multitude of specialized techniques that have applications in almost all areas of physics: astronomy, biophysics, chemistry, atomic physics, nuclear physics, solid-state physics, mechanics, acoustics, etc. Spectroscopy analyses not only visible light, but also electromagnetic radiation in all frequency ranges, elastic waves such as sound or seismic waves.

Here are the main instruments that measure light radiation:
