Laser protection tube and beam stop
On inverted microscopes, the safety beam guide and the beam stop serve as protection
against laser radiation emission and are located between the condenser base and the
transmitted-light detector (see Figure 20).

If you reorder a condenser base (Figure 20, item 3), be aware that the condenser
base is delivered without the beam stop (Figure 20, item 2).
The existing beam stop (Figure 20, item 2) must always be reinstalled. Please
consult the microscope's operating manual provided.
When using a condenser base with filter holder, always make sure that unused
filter holders are swung out of the beam path, and that the
laser protection tube covers the beam path.
When equipping multiple filter holders with filters, do so from bottom to top so that
the laser protection tube can cover the beam path to the greatest possible extent.
Do not swing in the filters during the scanning operation.
