Light Source Spectrum Data

This light is given different names depending on its wavelength and energy radio waves long wavelength low energy microwaves infrared visible light ultraviolet x rays and gamma rays short wavelength high energy.

Light source spectrum data. The emission spectrum for natural light generally follows the planck distribution in the visible part of the spectrum as we can see below. Double click the spectrum name or click the arrow to the right of the spectrum name to add the spectrum to the plotting window and the plotting legend. The 175w xe light source xe spectrum is a compact and light weight high intensity light source. White light can be generated by a variety of sources both in space and by artificial sources on earth.

For example the sun and other stars are sources of white light. The wavelengths that humans are typically able to visualize lie in a very narrow range between approximately 400 and 700 nanometers. Full spectrum typically refers to the completeness of a light source s spectral energy particularly when compared to natural light sources such as natural daylight. A standard illuminant is a theoretical source of visible light with a profile its spectral power distribution which is published.

Relative spectral power distributions spds of cie illuminants a b and c from 380 nm to 780 nm. The exact spectral composition of a light source can only be determined by specialized photometric equipment such as a spectrometer. Standard illuminants provide a basis for comparing images or colors recorded under different lighting. The emission spectrum of visible light arriving at the earth s surface from the sun.

It is especially suitable as a light source for spectroscopy microscopy optical scanning and industrial uses as well as for use with sp s popular digikröm monochromators and spectrographs. About light most objects in space give off radiate light. No color is dramatically favored over another although the intensity is highest in the light blue region around 460 nm.
