Title: Separation device for polarized light and production of converting device of polarized light
Inventor: HASHIZUME TOSHIAKI
IPC: G02F1/1335
Filed: 2000-03-22
Abstract: PROBLEM TO BE SOLVED: To rather accurately position a separation device for polarized light when the device is used for other devices by forming position identifying parts almost perpendicular to a plurality of interfaces. SOLUTION: The sheet glass block consists of, for example, six glass bodies 80, 81 of the basic structure laminated one another, and dummy glass bodies 82, 84 adhered to both ends of the block. In the block, the specified glass body 81 of the basic structure is positioned as protruding upward by the height H0 from the other glass body 80 of the basic structure. The sheet glass block is cut along the cutting faces 84a, 84b to obtain a substrate block to be used as a beam splitter for polarized light. In this process, the protruding part of the glass body 81 of the basic structure protruding upward is used as the referential position to decide the cutting faces so that the block is cut with high accuracy.  Thus, the dimensional accuracy of the beam splitter for polarized light can be increased, and when the beam splitter is used in combination with other separation device for polarized light or other instruments, the positioning accuracy of the beam splitter for the polarized light can be increased.
