2.6 Supplementary optics
The use of the supplementary optics ensures that you will achieve uniform, high intensity
illumination even when using light guides with a smaller bundle diameter than 9 mm.
If the illumination is carried out with imaging or focussing optical systems at the light guide exit,
perfectly uniform illumination is achieved by moving the supplementary optics out of the optical path.
To pivot the supplementary optics in and out, turn the pivot lever (6) clockwise or anti-clockwise to
the corresponding symbols. The supplementary optics always need to be pivot in or out as far as
they will go!
