Title:
偏光ビームスプリッタ及びその製造方法
Document Type and Number:
Japanese Patent JP6453217
Kind Code:
B2
Abstract:
A polarizing beam splitter is disclosed. The polarizing beam splitter includes a first polymeric prism (1360), a second polymeric prism (1370), a reflective polarizer (1350) that is disposed between and adhered to a hypotenuse of each of the first and second polymeric prisms, and a hardcoat (1380, 1385) that is disposed on each of the first and second polymeric prisms. The polarizing beam splitter includes an input major surface (1396a) and an output major surface (1396b). At least one of the input and output major surfaces has a pencil hardness of at least 3H. The polarizing beam splitter has a low birefringence such that when polarized light having a first polarization state enters the optical element from the input major surface and travels through at least 2 mm of the polarizing beam splitter and exits the polarizing beam splitter from the output major surface, at least 95% of light exiting the polarizing beam splitter is polarized has the first polarization state.
