4. Mount the optical window and then the window ring, along with the new seals, on the
assembly. Make sure to tighten the screws of the window ring uniformly in a diagonally
opposite sequence. In this way, you ensure that the ring is seated correctly.
5. If the optical windows and the window rings are not identical, make sure the lamp is on
the right side. The lamp should be on the side with the "shorter" window length.
Then mount the lamp and detector on the assembly.
If you have changed the path length by installing other optical windows, you then have
to configure the measuring system appropriately.
In any case, you must always perform an adjustment with liquids after disassembling and
assembling the windows.
Assemblies with an adjuster for the precision optical pathlength (POPL)
The precision optical pathlength (POPL) adjuster makes it possible to adjust the optical
pathlength to the exact distance necessary for the measurement.
POPL is only required for measuring systems with Easycal and optical pathlengths < 5 mm.
