"An example is the dichroic prism, used in some camcorders, which uses several coatings to split light into red, green and blue components for recording on separate CCD arrays. This kind of dichroic device does not usually depend on the polarization of the light. The term dichromatic is also used in this sense."

Wouldn't this be "trichoic prism" and "trichromatic"? 131.48.240.240 (talk) 06:50, 27 December 2007 (UTC)

Here the "dichroic" refers to each of the color-splitting dichroic mirrors in the color beamsplitting prism assembly. See here; I didn't find much on "trichroic prism" in books, but some journal articles use that term instead. Dicklyon (talk) 06:50, 27 December 2007 (UTC)


Being well aqcainted with a dichroic materials have different absorption for different polarisations I have been irritated on on the term being used for multilayer devices so I decided to check out. In wikipedia I find it clearly stated that the word dichroic has two distinct meanings, so OK I should not be irritated. But was the term really originally used for the multilayer structures and not the polarisation-anisotropic materials? References are needed!! —Preceding unsigned comment added by 150.227.15.253 (talk) 14:02, 2 June 2010 (UTC)
