Optical Isolator OIS9012-532
The optical isolator consists of a polarizing beamsplitter prism and a zero-order 1/4-wave plate, with the waveplate optical axis positioned at 45 degrees. Transmitted P-polarized light becomes circularly polarized after passing through the waveplate. After reflection and a second pass through the waveplate, it becomes S-polarized light and is reflected by the polarizing beamsplitter prism, providing optical isolation.
