Giovanni Battista Amici, (born March 25 , 1786 Modena, Duchy of Modena [Italy] died April 10 , 1863 Florence) astronomer and optician who made important improvements in the mirrors of reflecting telescopes and also developed prisms for use in refracting spectroscopes (instruments used to separate light into its spectral components).

An OLED, by contrast, emits its own light eliminating the need for a separate light source and requiring only about a third as much power as an LC D.Thedevice consists of a sandwich of organic compounds (complex carbon-based molecules) that emits light at a particular wavelength (and so a particular colour) when stimulated by an electric current.
Eddy Current Separation (ECS) is a classic method to separate light metal (aluminum) from plastic in the recycling industry.
Because liquid crystals cannot emit light, an LCD must include a separate light source.
Most processes rely on density differences to separate light minerals from heavier ones, so the ore is crushed and ground to release the ore minerals from the gangue.
"Mine is just organized: shoes with shoes, clothes with clothes," he said, but his parents complicate things by wanting him "to keep things separate: light jeans with light jeans, shorts with shorts, shirts and everything on hangers".
You focussed manually, of course, and there was nothing to help you calculate the exposure; either you carried a separate light meter, or you clipped one awkwardly to the top of the camera, or, if you were cool, you guessed.
DWDM splits a light wave into separate colors and then sends these separate light waves onto a single strand of fiber optic cable.
While LCD screens need a backlight to illuminate their crystals, OLED does not need a separate light source.
