The optionally available UV cut filter for reflection measurements or
the polarization filter for reflection measurements can be exchanged
by simply removing with your finger the original reflection optics cover
and replacing it with the desired filter cover. The cover is holding by a
magnet:
The UV cut filter is used to avoid wrong measurements when measur-
ing samples with optical brighteners. Measurements correspond to
measurement condition M2 of ISO 13655:2009
The Polarization filter is used when measuring shiny surfaces. Mea-
surements correspond to measurement condition M3 of ISO 13655:2009
When the polarization filter is mounted, measuring

