Basics of spectrometers and spectroscopy
The spectroscope is an instrument that separates white or near-white light into constituent colored bands as in a rainbow. The spectra can be projected onto a screen, viewed through a lens assembly, or photographed. The most elementary spectroscopes consisted of a single prism as used by Isaac Newton, described in an early treatise. He caused […]
