A homogeneous circular polarizer passes one handedness of circular polarization unaltered and blocks the other handedness. This is similar to the way that a linear polarizer would fully pass one angle of linearly polarized light unaltered, but would fully block any linearly polarized light that was orthogonal to it.
Some models have polarized lenses, made of Polaroid polarized plastic sheeting, to reduce glare caused by light reflected from non-metallic surfaces such as water (see Brewster's angle for how this works) as well as by polarized diffuse sky radiation (skylight). This can be especially useful to see beneath the surface of the water when fishing.
Linearly-polarized light may also defeat the action of the anti-aliasing filter (low-pass filter) on the imaging sensor. Circular polarizing photographic filters consist of a linear polarizer on the front, with a quarter-wave plate on the back. The quarter-wave plate converts the selected polarization to circularly polarized light inside the ...
A great pair of sunglasses is integral to pretty much every outfit during the summertime. Whether you’re spending the day by the beach, on a hike or just running errands around town, sunglasses ...
Polarization is important in radio communications because, for instance, if one attempts to use a horizontally polarized antenna to receive a vertically polarized transmission, the signal strength will be substantially reduced (or under very controlled conditions, reduced to nothing).
Finally, the retailer's optical department also offers options that are important to corrective eyewear buyers, including: HD progressive and polarized lenses Transitions photochromic lenses
