Lens  n.  (pl. lenses)  (Opt.) A piece of glass, or other transparent substance, ground with two opposite regular surfaces, either both curved, or one curved and the other plane, and commonly used, either singly or combined, in optical instruments, for changing the direction of rays of light, and thus magnifying objects, or otherwise modifying vision. In practice, the curved surfaces are usually spherical, though rarely cylindrical, or of some other figure. Lenses Note: Of spherical lenses, there are six varieties, as shown in section in the figures herewith given: viz., a plano-concave; b double-concave; c plano-convex; d double-convex; e converging concavo-convex, or converging meniscus; f diverging concavo-convex, or diverging meniscus.
Crossed lens (Opt.), a double-convex lens with one radius equal to six times the other.
Crystalline lens. (Anat.) See Eye.
Fresnel lens (Opt.), a compound lens formed by placing around a central convex lens rings of glass so curved as to have the same focus; used, especially in lighthouses, for concentrating light in a particular direction; so called from the inventor.
Multiplying lens or Multiplying glass (Opt.), a lens one side of which is plane and the other convex, but made up of a number of plane faces inclined to one another, each of which presents a separate image of the object viewed through it, so that the object is, as it were, multiplied.
Polyzonal lens. See Polyzonal.

The dog may lie in a sunny spot; but what dog ever created artificial heat or condensed by a lens the sun's heat on a particular point? The hen may lay and incubate an egg; but what hen ever invented an incubator to save her long sitting in one pose or place, or studied the development of life in and from the egg she produced? The ox may select the ...

... principle, represented in the sperm-cell by a spermatozooen, must be imparted to a germ-cell in order to effect impregnation. After touching each other, separate them immediately, and observe the result. If, with the aid of a powerful lens, we directly examine the spermatozooen, it will be perceived that, for a short time, it preserves its dimensions and retains all its material aspects. But it does not long withstand the siege of decay, and, having fulfilled its destiny, ...

The process, however, is a slow one, and if we study these sand grains under a lens we may be surprised to see that, though their corners and edges have been blunted, they are yet far from the spherical form of the pebbles from which they were derived. The grains are small, and in ...

... the change, for this reason—that the second wrong presents itself to him in the guise of the only practicable right. The action which before commission has been seen with that blended common sense and fresh untarnished feeling which is the healthy eye of the soul, is looked at afterwards with the lens of apologetic ingenuity, through which all things that men call beautiful and ugly are seen to be made up of textures very much alike. Europe adjusts itself to a fait accompli, and so does an individual character—until the placid adjustment is ...

... picture. It is so strong and clear that though it is such a long distance away it shines down upon the object that is to be photographed and reflects its image through a lens in the camera upon a plate which is sensitized (that is, coated with a sort of gelatine that is so sensitive that it holds the impression cast upon it until by the aid of certain acids and processes it can be made permanent, that is, lasting). I am afraid I have not succeeded in explaining ...

... visited Professor Amici, who showed him his microscopes "magnifying (it was said) two thousand diameters." Emerson hardly knew his privilege; he may have been the first American to look through an immersion lens with the famous Modena professor. Mr. Emerson says that his narrow and desultory reading had inspired him with the wish to see the faces of three or four writers, Coleridge, Wordsworth, Landor, De Quincey, Carlyle. His accounts of his interviews with these ...

In this window was hung almost his whole stock, and a table before it was covered with his work and tools. He was stooping over it, his lens in his eye, busy with a watch, of which several portions lay beside him protected from the dust by footless wine-glasses, when the laird and Cosmo entered.

... or whether we are born blind; but spiritually, it is the chief necessity of our lives that we should be able to see straight morally. Yet that is what we can seldom or never do. Modern education, particularly education in France, provides us at once with a double psychic lens, and a side-squint into the bargain! Seeing straight would be too primitive and simple for us. But Christ says, 'If thine eye be evil, thy whole body shall be full of darkness.' Now this word 'evil,' as set in juxtaposition to the former term 'single,' ...

Fine lines, hardly perceptible to the most penetrating lens, show themselves in transverse circles. These are the first signs of segmentation. A contraction appears in the front hyaline part, marking the head. An extremely thin opaque thread runs down either side. This is the cord of tracheae communicating between one breathing-hole ...

... younger ones; a fact on which this little orchid, like many another plant that arranges its blossoms in long racemes, depends. Let us not note for the present what happens in the older flowers, but begin our observations, with the help of a powerful lens, when the bee has alighted on the spreading lip of a newly opened blossom toward the top of the spire. As nectar is already secreted for her in its receptacle, she thrusts her tongue through the channel provided to guide it aright, and by the slight contact with the furrowed ...

... correctly placed, vertically in relation to that particular sitter, behind whom the figure appeared, and not so horizontally, this figure had not only not been impressed on the plate simultaneously with the two gentlemen forming the group, but had not been formed by the lens at all, and that, therefore, the psychic image might be produced without a camera. I think this is a fair deduction. But still the question obtrudes: How came these figures there? I again assert that the plates were not tampered with by either myself or any one ...

For a spiritual film is other than a photographic one. A poet's lens is endowed with a seeing eye, an insight, and a faculty to choose and compose. Hence the difficulty in tracing the footsteps of Fancy—in locating its cave, its nest, or its Kaaba. His pine-mosque we could find anywhere, at any altitude; his vineyards, ...

It draws their power of love together into a fixed point, just as the lens of a burning-glass concentrates the vague warmth of the sun into one small and fiercely illuminated area. It is a form of selfishness, I suppose, but it is a selfishness nature imposes upon us. And it is sanctified by the end it serves. At every turn, now, I find that I am thinking of my children. ...

There is therefore a peculiar equanimity and harmony about the look of lines of this kind, differing, I think, from the expression of any others except the circle. Beyond the point a the curve may be imagined to continue to an infinite degree of smallness, ...

By far the greatest of these scientific inventions are those which depend upon the lens.

The divine light, in passing through such a medium, would have been darkened and obscured. The lens through which the heavenly rays are to be transmitted must first be prepared and polished. The intellectual eye itself must be gradually accustomed to the light. Hence it is that all revelation has been progressive, commencing, in the infancy of our race, with ...

A camera obscura may be described as consisting of two parts—a lens in front, and a darkened chamber behind; but in the eyes of fishes, as in the brute and human eye, we find a third part added: there is a lens in the middle, a darkened chamber behind, and a lighted chamber, or rather vestibule, in front. Now, this lighted vestibule—the cornea—is wanting ...
