Spot Size Tables
The following tables show the optical data of the different device types. The values in the tables are ex-
emplary, intermediate measurement distances must be determined by interpolation. If the measuring
distance (= focused distance) differs from the adjusted or specified, a measurement is also possible, but
the spot size changes (usually it is larger, see
Calculation of the spot size diameter outside the
focused distance
).
Measuring distances
at manually focused optics are specified
from lens front, at motorized optics from the protection window.
