4 unusual facts about Optical resolution


Diphenylethylenediamine

The chiral diastereomer, which is of greater value, can be resolved into the R,R- and S,S- enantiomers using tartaric acid as the resolving agent.

Optical resolution

Rayleigh defined the somewhat arbitrary "Rayleigh criterion" that two points whose angular separation is equal to the Airy disk radius to first null can be considered to be resolved.

A key measure of the quality of atmospheric turbulence is the seeing diameter, also known as Fried's seeing diameter.

Square meters per pixel

Square meters per pixel (pixel) is the common unit of resolution for remote digital imaging of the surfaces of terrestrial objects of the Solar System, including the Earth.
