Project:
Indirect inspection of specular sample through a bore.
Client:
Inspection Machine Manufacturer
Application:
Customer needed to inspect a specular sample on the opposite side of
a panel through a bore in the panel.
Challenge:
The sample was not directly visible through the hole in the panel and
the bore was too small to accommodate the O.D. of a standard Navitar lens.
Navitar Solution:
Navitar designed a tapered front housing to be used in the front of an
existing Navitar Zoom 6000 system. This front assembly was machined with
a tip small enough to protrude through the bore of the panel, with the
end cut at 45 degrees. At the end of the assembly a mirror was installed
facing toward the camera to “see around the corner" of the
panel wall making the sample visible. Navitar designed the front assembly
with consideration for the required working distance and field of view.
This front assembly was also designed to be used with co-axial lighting
to ensure optimal viewing of the target. A viewing port was machined into
the side of the assembly to allow the passage of light from object, to
mirror, to lens, to camera.
