7.3 Cleaning the optics

The reflection optics are equipped with a air blowing system which
is activated when the reference white covering the optics aperture is
moved to open position for measurements. It makes sure a small air
circulation is blowing out the aperture during measurements avoiding
fibers and dust to enter the optical parts.
However it still is recommended to inspect and clean this reflection
optics from time to time.
The reflection optics are accessible by removing the spectral unit from
the platform and removing the reference white and aperture ring.
Use dry compressed air to clean and blow out particles which are lightly
attached to the optical components.
Also clean the transmission optics by cleaning the white ceramics dif-
fusor with a soft lens tissue and/or a non colored solvent.
