- a brand of material for producing polarized light from unpolarized light by dichroism, consisting typically of a stretched sheet of colorless plastic treated with an iodine solution so as to have long, thin, parallel chains of polymeric molecules containing conductive iodine atoms. It is used widely in optical and lighting devices to reduce glare.
- the first brand of instant camera, developed by Edwin H. Land and marketed since 1948.
- a print made by such a camera.
- a type of plastic sheet that can polarize a transmitted beam of normal light because it is composed of long parallel molecules. It only transmits plane-polarized light if these molecules are parallel to the plane of polarization and, since reflected light is partly polarized, it is often used in sunglasses to eliminate glare
- any of several types of camera yielding a finished print by means of a special developing and processing technique that occurs inside the camera and takes only a few seconds to complete
- sunglasses with lenses made from Polaroid plastic
- of, relating to, using, or used in a Polaroid Land Camera
