What inspection variables should be evaluated?
Verify object-space field, working distance and permitted height variation even with telecentric optics. Validate using a calibration artefact.
What lighting geometry fits this inspection task?
Backlighting separates an outline from its background and is a useful starting point for edges, holes and position checks. Confirm that the fixture leaves the optical path clear. Compare diffuse and collimated backlights, especially where curved or transparent edges change with viewing angle.
Keep the camera and lens fixed. Capture the centre and corners at the same exposure, then repeat at different part heights. Check edge profiles and position repeatability. A telecentric lens can reduce magnification changes within its specified range; calibration is still necessary.

Before choosing a configuration?
For selection, specify the field of view, smallest target feature, height variation, cycle time and installation space. Use the specific product page and drawing to verify electrical ratings, dimensions and compatibility.
Combining telecentric imaging and backlighting?
Choose the lens and illumination from the measurement field and depth range. Telecentric imaging and directional illumination address different parts of the edge-imaging problem; neither removes the need for calibration and validation.
Move a calibrated target through the allowed depth and lateral positions. Check edge sharpness and measured dimensions with fixed settings. Verify performance at the field corners and with the actual part material.
