Introduction

Jasco NFS 300
Jasco NFS 300

Crystal anisotropy of materials, optical rotatory power, and dynamics under a magnetic field are known to affect polarization of transmitted light through certain materials. In practical applications, they are used for high-density recording and display devices. Combining a polarization maintaining fiber probe and the transmission option of the JASCO Near-Field System, a sample was irradiated by a linear polarized beam or a circularly polarized beam and the polarization state of the transmitted light was analyzed. The anisotropy for the sample observed in the nanoscale.
