Very scratch-resistant and schmutabweisender circular polarization filter, the polarizations reliably prevented.
Oblique on electrically non-conducting surfaces (eg glass, plastic, paint or water *) incident light is in the reflection, depending on the angle of incidence greater or lesser extent ³polarisiertÊ: Its waves oscillate then mainly or exclusively in a ³PolarisationsebeneÊ held out in all directions. Because of this property of the mirrored light is with polarization filters (or short pole filters) possible, mitigate reflections to possibly eliminate entirely, but to also increase. It is also possible with them to color more intense blue sky or to enhance the color saturation of a landscape by eliminating the bluish scattered light veil. Their action is not by digital image processing subsequently replaced.

* The electrical conductivity of water is too low to prevent polarization.

Polarizer have in a rotary mount between protective glass plates a polarization film which transmits only in a plane oscillating light. Depending on the filter rotational position polarized light is completely, partially transmitted or not. Normal unpolarized (= mixed polarized) light is 2x weakened as a neutral density filter ND about half. Allegedly substantially light permeable polarizing filter can do that for physical reasons only through reduced polarization effect! The transmission gain is therefore at the expense of the desired effect.

Circular suitable for all cameras, even those with beam splitter before AFSensor or TTL Belichtungsmeßzelle (are for which linear polarizing unusable). The HR Digital Circular are characterized by the following features:
  • The transmittance (light transmittance) is particularly high and the reflection particularly low thanks to a seven-multi-coating, which double images and scattered light are better suppressed.
  • A deposited as an eighth layer extremely scratch-resistant and water- and dirt-repellent protective layer makes the glass surfaces more resistant. It does not affect the transmission, keeps the surface clean longer and allows easy cleaning.
  • The brass version produced no quality-reducing mechanical stresses in the glass filters because of their very low thermal expansion, even with extreme temperature fluctuations. Furthermore, the risk of jamming is minimized in the filter thread of the lens, because brass is especially slippery.
