Cross polarization is a technique that uses two polarizing filters – one on the light source and on e on the camera lens – to get rid of unwanted specular reflections. The following slideshow illustrates the effect at varying degrees, depending on the orientation of the filters with respect to each other. The aim of this study was to assess the influence of a polarizing filter on the accuracy of dental shade matching using digital photography. A comparison was performed using ΔEab parameters between CIE L*a*b* values obtained from digital images taken under two different conditions (with direct light … polar_eyes - Cross Polarization Filter Improves lab communication - eliminates reflections on the teeth that are caused by the flash For International Orders (outside the U.S.) , please click here AIMS: Quantifying the ex vivo growth of complex multispecies dental biofilms using cross-polarization 1310-nm optical coherence tomography (CP-OCT) system was investigated. METHODS AND RESULTS: Bacterial microcosms, which were derived from plaque samples of paediatric subjects, were incubated in a biofilm reactor system containing discs of different dental materials for 72 h with daily sucrose pulsing (5×).

The polarization of the rainbow is caused by the internal reflection. The rays strike the back surface of the drop close to the Brewster angle. Polarizing filters can be rotated to maximize or minimize admission of polarized light. They are mounted in a rotating collar for this purpose; one need not screw or unscrew the filter to adjust the effect. Amazon.com: polarizing filter sheets.

Well, that’s how Polarizer filters work, too.
