Safety
2.2 Safe Handling of the Device
Read the following applicable safety instructions carefully and completely.
Follow the instructions for your own safety, the safety of other people, and to
avoid damage to the device and the connected technical equipment. Hazards
going beyond the general safety instructions are referred to separately at the
relevant points in this manual.
CAUTION
Eye damage
•Do not look directly through the lens.
CAUTION
Cutting injuries caused by glass breakage
The lenses of the objective are made of glass.
•Protect the objective against impact and do not drop it.
•In case of glass breakage do not touch any breakage edges.
•In case of glass breakage use cut-resistant protective gloves.
•Dispose of glass breakage using appropriate waste
containers.

Extension rings can reduce the ideal imaging performance specified in the
manual.
They mainly cause a change in the working distance. The magnification also
changes, but only very slightly.
The working distance is reduced by approximately the thickness of the
extension ring divided by the square of the magnification.
