In the Articulata we can commence a series with an
optic nerve merely coated with pigment, and without any other mechanism; and from this low stage, numerous gradations of structure, branching off in two fundamentally different lines, can be shown to exist, until we reach a moderately high stage of perfection.
There was a morning when Aileen tripped in to work with a slightly bruised eye; and Tildy's solicitude was almost enough to heal any
optic.
And it seemed to me that his eyes were strange, not only the expression, but the physical seeming, as though the
optic nerves and supporting muscles had suffered strain and slightly twisted the eyeballs.
Just as a photographic plate receives a different impression of a cluster of stars when a telescope is part of the intervening medium, so a brain receives a different impression when an eye and an
optic nerve are part of the intervening medium.
He scarce had ceas't when the superiour Fiend Was moving toward the shore; his ponderous shield Ethereal temper, massy, large and round, Behind him cast; the broad circumference Hung on his shoulders like the Moon, whose Orb Through
Optic Glass the TUSCAN Artist views At Ev'ning from the top of FESOLE, Or in VALDARNO, to descry new Lands, Rivers or Mountains in her spotty Globe.
He brought our Saviour to the western side Of that high mountain, whence he might behold Another plain, long, but in breadth not wide, Washed by the southern sea, and on the north To equal length backed with a ridge of hills That screened the fruits of the earth and seats of men From cold Septentrion blasts; thence in the midst Divided by a river, off whose banks On each side an Imperial City stood, With towers and temples proudly elevate On seven small hills, with palaces adorned, Porches and theatres, baths, aqueducts, Statues and trophies, and triumphal arcs, Gardens and groves, presented to his eyes Above the highth of mountains interposed-- By what strange parallax, or
optic skill Of vision, multiplied through air, or glass Of telescope, were curious to enquire.
In the common mole the eye is extraordinarily small but perfect, though many anatomists doubt whether it is connected with the true
optic nerve; its vision must certainly be imperfect, though probably useful to the animal when it leaves its burrow.
But, on the other hand, they connect diagonally, and the sprawling outlines run off in great slanting waves of
optic horror, like a lot of wallowing seaweeds in full chase.

Optic Cleaning kits include everything you need to quickly and thoroughly clean fibre
optic end-faces and splices to save you time and money.
The growing government expenditure on technological advancement in the industrial sector and the increasing private investment in research into microwaves and other areas in
optics are also likely to be a key driver for the electro-optic modulators market over the forecast period.
One of the largest challenges associated with specifying
optics for ultrafast lasers --where pulse durations are picoseconds or shorter--is the potential for side-effects, such as dispersion and laser damage, which could critically affect the quality of the beam and system performance.
Purpose of the activity was to celebrate International Day of Light in collaboration with The Abdus Salam International Centre for Theoretical Physics, Optical Society of America (OSA), The International Society of
Optics and Photonics (SPIE) and The International commission of
Optics (ICO).
