RETARDER FILM |
||||
|
Retarder film is a clear birefringent material that changes the phase of a polarized beam of light. A quarter-wave can be used to convert linearly polarized light (oriented at 45° from the direction of the fast/slow axis) into circularly polarized light. Conversely, it can convert a circularly polarized beam into linearly polarized light. |
