Hello,
I would like to know what general differences between linear and polarizing filters circuaren there? and what is what?

Antwort von Kollektor:
When linear polarizing filter is the failure of light always the light of a certain polarization, so it vibrates in exactly one direction and linearly polarized light is called.
For circular polarizing filters, the linearly polarized light then still in circularly polarized light is converted. This is achieved by the light of linear polarization through a so-called »/4-Plättchen is sent, which for various polarized light has different propagation speeds. The optical axis of the »/4-Plättchens this has increased by 45 ° from the polarization direction of the linear polarizing filter will be rotated. It now has circularly polarized light to the linearly polarized light with the technical advantage that no preferred direction of oscillation and is therefore in the further processing of any traces of the selected show more polarization direction.
For videographers: Zikulare Polarizing filters have the advantage that the automatic exposure and autofocus on most cameras work.
