13 Aligning and focusing the fiber optic head
The fiber optic head has to be aligned on the target. It is important to ensure that
the beam path is not obstructed. If the pyrometer has a fiber optic, it could be
necessary to focus the measuring head additionally.
For that, the laser pointer is to be connected to the fiber optic and to be activated
by using a button!
For focal adjustment loosen the shown socket screw (hexagon socket screw
DIN 916) with a wrench (DIN 911) and shift the internal body of the tube towards
the lens tube.
Due to the O-ring sealing between the internal body of the tube and the lens tube
the focal adjustment must be carried out very slowly so that the air pressure in the
space between lens and internal body of the tube can be be equalised.
Focus the sensing head until the spot light is shown as a sharp round laser
spot in the target area. In bright daylight or in an excessively lit environment it is
recommendable to dim the area around the target.
