n.
An enlarged representation of a microscopic object, produced by throwing upon a sensitive plate the magnified image of an object formed by a microscope or other suitable combination of lenses.
a.
An arrangement of two lenses for a microscope, designed to correct spherical aberration and chromatic dispersion, thus rendering the image of an object more clear and distinct.
n.
A tool on which lenses are fastened in a group, for polishing or grinding.
n.
An exhibition in which a series of views in various parts of the world is seen reflected by mirrors through a series of lenses, with such illumination, etc., as will make the views most closely represent reality.
n.
An optical instrument consisting of two lenses set in a light frame, and worn to assist sight, to obviate some defect in the organs of vision, or to shield the eyes from bright light.
n.
The science of the refraction of light; that part of geometrical optics which treats of the laws of the refraction of light in passing from one medium into another, or through different mediums, as air, water, or glass, and esp. through different lenses; -- distinguished from catoptrics, which refers to reflected light.
n.
A concave tool used in grinding lenses or the speculums of telescopes.
n.
An instrument with two lenses, by which an image of a single picture projected upon a screen of ground glass is made to present an appearance of relief, and may be viewed by several persons at once.
n.
The lens, or combination of lenses, at the eye end of a telescope or other optical instrument, through which the image formed by the mirror or object glass is viewed.
n.
An instrument for measuring the curvature of spherical surface, as of lenses for telescope, etc.
n.
A false image formed in a telescope by reflection from the surfaces of one or more lenses.
n.
The art or process of exhibiting luminous images, especially those of external objects, in a darkened room, by arrangements of lenses or mirrors.
n.
An optical instrument, consisting of a lens, or combination of lenses, for making an enlarged image of an object which is too minute to be viewed by the naked eye.
n.
A lamp with lenses or reflectors to collect the rays of light and throw them in a given direction; -- used in lighthouses.
n.
The diaphragm used in optical instruments to cut off the marginal portions of a beam of light passing through lenses.
v. t.
A hard, brittle, translucent, and commonly transparent substance, white or colored, having a conchoidal fracture, and made by fusing together sand or silica with lime, potash, soda, or lead oxide. It is used for window panes and mirrors, for articles of table and culinary use, for lenses, and various articles of ornament.
v. i.
To have the power of causing objects to appear larger than they really are; to increase the apparent dimensions of objects; as, some lenses magnify but little.
n.
an optical instrument of tubular shape containing an arrangement of lenses and mirrors (or prisms), allowing a person to observe a field of view otherwise obstructed, as beyond an obstructing object or (as in submarines) above the surface of the water.
