  A prism would separate the light into a spectrum, which probably isn't what you want. If the window isn't visible in your shot, you could use what's sometimes called a ***silk***, which is more often made of muslin or other semi-translucent material.

  I would investigate hanging a row of round acrylic ("Plexiglas") rods like a curtain which would serve rather like a big amorphous "Fresnel lens".
  
  Else, you could use the traditional "brute-force" method used by big-budget production companies:
  
  1. **Giant lamps** outside the window focused through the opening. They commonly use expensive (and very bright) HMI lights for "punching through" sunlight levels.
  2. **Big reflectors** that catch extra sunlight and reflect it in through the window. Metalized reflective fabric stretched on a big frame
