3.3 Option side view prism
The below shown side view prism may be
employed for direct tube wall inspection.
To attach the side view prism, the
straight view optics need to be
screwed–off. Be careful to not unscrew
the distance ring. When screwing the side
view optics onto the head and vice versa,
be careful to find the exact beginning of
the thread and not to damage the o-ring.
The focus range can be adjusted easily
as follows to achieve ‘sharp images’:
NEAR FOCUS:
Upon the position the LED’s start / stop
illuminating (the camera needs to be
switched on after closing the camera head)
this is the most closest view possible.
Near view = move lens away from camera
housing.
FAR VIEW:
The end position of the side view optics to
the distance ring is the farest focus point
within the illumination capabillity of the
camera head. Do not tighten the thread
onto the distance ring! Far view= move
lens towards camera housing.
Softly clean prism surface with a
cotton-tip (Q-tip) dipped into 80% alcohol.
Always be extremely care-
ful to not let dirt and dust
enter the electronics of the
camera head.
Only open and close the
camera head if the comple-
te system is switched off.
Never fix centering rings to
the sideview mirror.
The sideview optical adap-
ter is only splash water-
proof!
