What is polychromatic light?
Polychromatic light is light (visible and invisible) that consists of many different wavelengths. For example, the white light from a halogen light source is polychromatic and contains all wavelengths between approx. 360 and 2500 nm. The light from white light LEDs and laser-pumped plasma light sources is also polychromatic. Monochromatic light, i.e. light with only one wavelength, can be isolated from polychromatic light in a monochromator.
What is the difference between polychromatic and monochromatic light?
Polychromatic light consists of many wavelengths, whereas monochromatic light consists theoretically of a single wavelength.
What are examples of polychromatic light sources?
Halogen light sources, white light LEDs and laser-pumped plasma light sources are examples of polychromatic light sources.
How can monochromatic light be made from polychromatic light?
In a monochromator, monochromatic light can be isolated from polychromatic light.
