Fraction :: Fraction (v. t.) To separate by means of, or to subject to, fractional distillation or crystallization; to fractionate; -- frequently used with out; as, to fraction out a certain grade of oil from pretroleum..

Fractionate :: Fractionate (v. t.) To separate into different portions or fractions, as in the distillation of liquids..

Anaclastic :: Anaclastic (a.) Produced by the refraction of light, as seen through water; as, anaclastic curves..

Uniaxial :: Uniaxial (a.) Having but one optic axis, or line of no double refraction..

Eriometer :: Eriometer (n.) An instrument for measuring the diameters of minute particles or fibers, from the size of the colored rings produced by the diffraction of the light in which the objects are viewed..

Diacaustic :: Diacaustic (a.) Pertaining to, or possessing the properties of, a species of caustic curves formed by refraction. See Caustic surface, under Caustic..
