- Title:Double-Layer Negative Dispersion Retarder Using Negative Birefringence Materials
- Seungbin Yang, Anoop Kumar Srivastava, and Ji-Hoon Lee (Chonbuk Nat'l Univ., Korea)
Abstract: Generally, optically anisotropic materials have a positive dispersion (PD) of birefringence (¥Än). PD means that birefringence of the medium decreases with increasing the wavelength (¥ë) of light. PD marerials have a different phase retardation ¬¤¡Õ2¥ð¥Änd/¥ë at different ¥ë and this degrade the performance of the compensation film. To overcome this problem, the retarder with ND of birefringence has been studied. We made a double-layer ND retarder using two uniaxial films which were made of polystyrene (PS) and polymethylmethacrylate (PMMA).
