Title: Polarizing element and optical pickup using the same
Inventor: NISHI NORIAKI
IPC: G02B5/04
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To improve the optical performance and to lower the cost by widening a range of material selection by selecting a material which has two close refractive indexes among three refractive indexes for object biaxial crystal. SOLUTION: A refractive index elliptic body has main refractive indexes nx to nz as main values. Then OA1 and OA2 are main optical axes and the directions of main axes X to Z of the refractive index elliptic body match refractive index axial azimuths nx to nz (nx axis to nz axis) here. Thus, the element is formed of biaxial crystal represented as the refractive index elliptic body with refractive indexes nx to nz of optical characteristics and a polarizing element having two close refractive indexes among the three nx to nz is used. The polarizing element is formed of the biaxial crystal having nearly the same refractive indexes as to two axes and the two refractive index axial azimuths which are the same, so they can be handled as approximately one refractive index axial azimuth. Therefore, biaxial crystal like this is usable for an optical element which used only uniaxial crystal.
