Light polarized in the plane is said to be p-polarized, while that polarized perpendicular to it is s-polarized. At a special angle known as Brewster's angle , no p -polarized light is reflected from the surface, thus all reflected light must be s -polarized, with an electric field perpendicular to the plane of incidence.
Circular polarizer/linear analyzer [1] filtering unpolarized light and then circularly polarizing the result. A polarizing filter or polarising filter (see spelling differences) is a filter that is often placed in front of a camera lens in photography in order to darken skies, manage reflections, or suppress glare from the surface of lakes or the sea.
Mirrored coatings can be made any color by the manufacturer for styling and fashion purposes. The color of the mirrored surface is irrelevant to the color of the lens. For example, a gray lens can have a blue mirror coating, and a brown lens can have a silver coating. Sunglasses of this type are sometimes called mirrorshades. A mirror coating ...
One polarization is deviated by different refraction only: Rochon prism; Sénarmont prism; Both polarizations are deviated by refraction: Wollaston prism; Nomarski prism – a variant of the Wollaston prism where p-and s-components emerge displaced and converging towards each other; important for differential interference contrast microscopy
The lenses were made to a joint standard shared by the U.S. Army Air Corps and the U.S. Navy. As a result, the lens carried an "AN" (Army/Navy) specification number: the AN6531. The U.S. Government specified the shape of the lens and the color, which was initially a green tinted lens that transmitted 50% of incoming visible daylight.
Compounds with these properties consist of chiral molecules and are said to have optical activity. If a chiral molecule is dextrorotary, its enantiomer (geometric mirror image) will be laevorotary, and vice versa. Enantiomers rotate plane-polarized light the same number of degrees, but in opposite directions.
