2. Polarizing filter (photography) - Wikipedia

   en.wikipedia.org/wiki/Polarizing_filter...

   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.

3. Polarizer - Wikipedia

   en.wikipedia.org/wiki/Polarizer

   A Polaroid polarizing filter functions similarly on an atomic scale to the wire-grid polarizer. It was originally made of microscopic herapathite crystals. Its current H-sheet form is made from polyvinyl alcohol (PVA) plastic with an iodine doping. Stretching of the sheet during manufacture causes the PVA chains to align in one particular ...

4. Polarimetry - Wikipedia

   en.wikipedia.org/wiki/Polarimetry

   Polariscopes make use of their polarizing filters to reveal properties of a gem about how it affects light waves passing through it. A polariscope may be first used to determine the optic character of a gem and whether it is singly refracting (isotropic), anomalously doubly refracting (isotropic), doubly refracting (anisotropic), or aggregate.

5. Polaroid (polarizer) - Wikipedia

   en.wikipedia.org/wiki/Polaroid_(polarizer)

   Polarizing sheets are used in liquid-crystal displays, optical microscopes and sunglasses. Since Polaroid sheet is dichroic , it will absorb impinging light of one plane of polarization, so sunglasses will reduce the partially polarized light reflected from level surfaces such as windows and sheets of water, for example.

6. Photographic filter - Wikipedia

   en.wikipedia.org/wiki/Photographic_filter

   Several close-up lenses may be used in combination; the optical power of the combination is the sum of the optical powers of the component lenses; a set of lenses of +1, +2, and +4 diopters can be combined to provide a range from +1 to +7 in steps of one. A split diopter has just a semicircular half of a close-up lens in a normal filter holder.

8. Optical rotation - Wikipedia

   en.wikipedia.org/wiki/Optical_rotation

   The phase velocity of light in a medium is commonly expressed using the index of refraction n, defined as the speed of light (in free space) divided by its speed in the medium. The difference in the refractive indices between the two circular polarizations quantifies the strength of the circular birefringence (polarization rotation),
