WebApr 12, 2024 · The optical fiber probe with a collimation mirror is fixed vertically above the PRILD. The emission spectra in the wavelength ranges of 200 to 1000 nm and 900 to 1750 nm are measured by IdeaOptics PG2000-Pro and NIR-17S, respectively. The CRI, CCT, and color coordinates are calculated from the measured emission spectrum. WebSep 19, 2024 · Atomic Emission Spectra. The electrons in an atom tend to be arranged in such a way that the energy of the atom is as low as possible. The ground state of an atom is the lowest energy state of the atom. When those atoms are given energy, the electrons absorb the energy and move to a higher energy level. These energy levels of the …
