3 System description
3.3 Stages
3.3.2 Fluor stage with accessories
Spacers
There are two types of spacers that can be used with the fluor stage:
Spacer type
Sample spacer (single
spacer)
Digitization/OD spacers
(pair of spacers)
The image below shows the sample spacer.
The digitization/OD spacers are used together with the digitization plate for digitization
of samples and for measurements of relative OD in the densitometry scan mode. The
digitization plate rests on the spacers, so that there is space for the sample between the
fluor stage and the digitization plate. The illustration below shows the digitization/OD
spacers.
The digitization/OD spacers can be used both for digitization and for OD measurements,
depending on the orientation and placement of the spacers. The illustation below shows
the orientation in which the spacers are used for digitization.

Function

area
