Analog Optical Alignment - Projector
6.2 Analog Optical Alignment - Projector
If a stereo solar cell is already installed
on Projector No. 1, inspect the surface
of the cell for cracks, chipping, or other
damage. If the cell appears to require
replacement, remove the mounting
bracket from the projector and replace
the cell and mounting block assembly.
Clean the lens surfaces with a cotton
swab moistened with glass cleaner. But
keep in mind that you may find, during
optical preamp adjustment, that it will be
necessary to remove and inspect the lens
if the high-frequency response is not
correct.
If the lens is removed, clean the lens as
indicated above and look through the
lens at a bright light. Repeated alternate
heating and cooling of the lens can cause
oil or other contaminants to enter the
lens barrel. Verify that there is a clear,
unobstructed light path through the lens
and that the edges of the slit are sharp
without cracks or corrosion. Fit a new
lens assembly if you are unable to clear
the optical path through the slit.
