Polarization beam splitter(PBS)
Product description:
    Polarization beam splitter(PBS) is the core part of LCOS micro projection technique. LED optical source give out light and  be gathered which of their divergent angle is within 16 degree by spherical lens to inject into PBS, P beam transmit out ,S beam reflect to LCOS surface, LCOS based on projection single reflect directly or reflect P beam switched by S beam getting into PBS again, and through projection lens to display image.
