I Backscatter setup - one way mirror

  1. Apr 13, 2016 #1
    I'm constructing a backscatter optical setup for my thesis and I'm trying to find something like a pellicle mirror (or pellicle beamsplitter) that is transparent to light from one side but reflects from the other side. I can use a conventional pellicle beamsplitter, however since my backscattered intensity is already low enough I wanted to try and not discard half of my beam. Any suggestions? thanks.

    True one-way mirrors violate reciprocity, and so creating one requires some care- optical isolators often use Faraday rotation, for example.
