Op"tic*al*ly, adv.

Definition: By optics or sight; with reference to optics. Optically active, Optically inactive (Chem. Physics), terms used of certain metameric substances which, while identical with each other in other respects, differ in this, viz., that they do or do not produce right-handed or left-handed circular polarization of light.

– Optically positive, Optically negative. See under Refraction.

OPTIC

Op"tic, n. Etym: [From Optic, a.]

1. The organ of sight; an eye. The difference is as great between The optics seeing, as the object seen. Pope.

2. An eyeglass. [Obs.] Herbert.

Op"tic, Op"tic*al, a. Etym: [F. optique, Gr. oculus eye. See Ocular, Eye, and cf. Canopy, Ophthalmia.]

1. Of or pertaining to vision or sight. The moon, whose orb Through optic glass the Tuscan artist views. Milton.

2. Of or pertaining to the eye; ocular; as, the optic nerves (the first pair of cranial nerves) which are distributed to the retina. See Illust. of Brain, and Eye.

3. Relating to the science of optics; as, optical works. Optic angle (Opt.), the angle included between the optic axes of the two eyes when directed to the same point; -- sometimes called binocular parallax.

– Optic axis. (Opt.) (a) A line drawn through the center of the eye perpendicular to its anterior and posterior surfaces. In a normal eye it is in the direction of the optic axis that objects are most distinctly seen. (b) The line in a doubly refracting crystal, in the direction of which no double refraction occurs. A uniaxial crystal has one such line, a biaxial crystal has two.

– Optical circle (Opt.), a graduated circle used for the measurement of angles in optical experiments.

– Optical square, a surveyor's instrument with reflectors for laying off right angles.
