a pair of two similar or equal things; couple

a man’s close-fitting jacket, with or without sleeves. Men in Europe wore doublets from the 1400s to the 1600s

{n} a pair, waistcoat, patent, false stone

A quantum state of a system with a spin of 1/2, such that there are two allowed values of the spin component, -1/2 and +1/2

Two of the same kind; a pair; a couple

A lens system comprising two elements, used to reduce chromatic aberration

A doublet (also dublette) is a gem made from two layers in order to save expenses; the lower part of the composite stone is glass or a non-precious stone, the top is the more valuable stone Many different types of doublets have been manufactured (including opal doublets) One common doublet contains a layer of real garnet and a layer of glass A thin, red garnet top is glued to a colored glass bottom A green glass bottom with a red garnet top layer produces an emerald-like stone A diamond is enlarged by cementing it to a crystal base

quilted garment, stuffed with cotton or waste material, stitched and worn under a hauberk

A form of gemstone trickery that was devised to allow inexpensive materials to imitate the more valuable gemstones before modern synthetics were available A doublet can take several forms but always involves a fake gemstone produced by gluing together two different materials to form an illusion A very common one in Victorian times was the garnet and glass doublet This involved a red garnet top, glued to a colored glass bottom The refractive properties of a faceted stone are such that the red of the garnet only shows at odd angles, or if the stone is immersed in a special liquid with a high refractive index Thus, for example, a green glass bottom with a garnet top will give the appearance of a fine emerald because the top is a natural gemstone with cut facets, and a few natural imperfections, and the bottom is bright green which reflects throughout the stone The effect is hard to appreciate unless you've seen one

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

The electronic state of a molecule having one unpaired spin is termed a doublet (see °radical) This term is derived from spectroscopy: an unpaired spin can be either up or down with respect to a magnetic field, and these states have different energy, resulting in field-dependent pairs, or doublets, of spectral lines (See °triplet, °singlet )

A counterfeit gem, composed of two pieces of crystal, with a color them, and thus giving the appearance of a naturally colored gem
