5.5.3 Manually Focusable Fiber Optic Lenses
Optics OL25: Just slightly open the lens locking ring for re-
leasing and locking the optics, as rear optics part rotates with
opening of the locking ring.
Optics OL12: Optics lock screw (allen screw) for releasing
and locking the optics.
Pull the rear optics part out of the tube to focus according to
the required measuring distance (laser beam is focused and
has the smallest diameter).
NOTE: Never pull on the flexible part of the light
guide to focus!
5.6 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 5.6.3 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.
