C-Mount adjustment
Pike
cameras
allow
the
precise
adjustment
of
the
back
focus
of
the
C-Mount
by
means
of
a
back
focus
ring
which
is
threaded
into
the
C-Mount
and
held
by
two
screws:
one
on
the
top
(middle)
and
one
on
the
right
side
of
the
camera.
The
mechanical
adjustment
of
the
imaging
device
is
important
in
order
to
achieve
a
perfect
alignment
with
the
focal
point
of
the
lens.
Individual
adjustment
may
be
required:
•
if
you
cannot
focus
correctly
at
near
or
far
distances
or
•
if
the
back
focal
plane
of
your
lens
does
not
conform
to
the
C-Mount
back-focus
specification
or
•
if
you
have
e.g.
removed
the
IR
cut
filter.
Do
the
following:
1.
Looking
in
front
of
the
lens
loosen
both
screws
on
the
top
(middle)
and
the
right
side
of
the
housing
(locations
as
shown
above
by
arrows)
with
an
Allen
key
(1.3
×
50;
order
code:
K
9020411).
2.
With
the
lens
set
to
infinity
or
a
known
focus
distance,
set
the
camera
to
view
an
object
located
at
infinity
or
the
known
distance.
3.
Rotate
the
C-Mount
ring
and
lens
forward
or
backwards
on
its
thread
until
the
object
is
in
sharp
focus.
Be
careful
that
the
lens
remains
seated
in
the
C-Mount.
4.
Once
focus
is
achieved,
tighten
the
two
locking
screws
without
applying
excessive
torque.
