Collimating a white light beam

  1. Aug 1, 2013 #1
    Dear all
    I need collimating light from a Xe arc source.
    More in details, the white light source is coupled to a monochromator. In fact I need a circular collimate light beam from the monochromator with a diameter of 1-2 mm.
    At the moment I am using a (rectangular) slit in the monochromator of 1.2 mm.
    Can you suggest me a possible solution?
    Thank you

    You are trying to collimate the monochromator output? That can be tricky. One possible solution is to launch the output into an optical fiber- a large multi-mode one should be fine- and collimate the fiber output. It's going to be very lossy, tho.

    What is your application?
