InSight™ In-line Video Inspection Station

InSight™ In-line Video Inspection Station  is a dedicated video station for the inspection of fiber optic connectors and photonic components.  All Krell polishing workholder fixtures can quickly engage with this system allowing  in-line inspection without the need to remove the connector/termini/chip/component from the polishing fixture.  This streamlines quality assurance and minimizes the change of component damage and contamination that can occur when removing and transfer parts back-and-forth between polisher and microscope.  Magnification levels can easily be change by the simple exchange of optical objectives.  InSight™ supports NOVA™, Scepter™, SpecPro™, FLex™, Radian™ and Proton polishing equipment and machines.

Load Workholder: Load the workholder onto the universal mount at a slight angle while the clamp is loose, then place it flush to the interfacing plate and tighten the clamp to secure (see Figure 2). The clamp can be adjusted to accommodate different workholders and custom fixturing. To adjust, first lift the handle while applying pressure to the center nut using a flathead screwdriver. Rotate the center nut to adjust the clamping position, then release the handle to engage (Figure 3). Figure 2. Loading SpecPro Workholder Setup 3. Illumination: Turn on the Epi-illumination (in-line) by twisting the knob on the top of the Insight (6). Depending on lab lighting conditions, the ‘Auto-Exposure’ option may need to be deselected within the Vision Software. The Epi-illumination allows for greater detail of surface defects when inspecting fibers. The external L.E.D gooseneck lamp allows for greater visual details of the surrounding sample. 4. Adjust Positional Stages: X Stage - Slide the microscope along the translational rail until centered under the sample. Slide and lock the Reference Stops in place on either side for quick viewing repeatability. Y and Z Stages - Use the coarse adjustments to quickly locate the sample in the viewfinder software, then use fine adjustments to obtain a precise image of the sample. Figure 3.
