V-Groove and FAU End-Face Inspection: Telecentric Imaging
What a V-groove / FAU end-face inspection must show and which optics fit each scale: coaxial telecentric imaging for the array overview, zoom + APO objective (total magnification = zoom x objective x 0.55) or microscope optics for single-fiber detail. Illustrated with four real camera images of a 4-fiber V-groove sample.
Inline Measurement Cycle Time
How to calculate inline measurement cycle time and station count: takt time vs cycle time, the per-part time budget, availability, worked examples for 2
Machine Vision Light Colour: Wavelength Selection Guide
How to choose machine vision light source colour and wavelength: same-colour vs complementary light, monochrome and colour camera pairing
Machine Vision Light Source Selection: Point, Ring, Coaxial
How to choose a machine vision light source: reflected vs transmitted light, and point, ring, telecentric parallel and coaxial types
Motorized Zoom Lens for AOI
AOI needs a wide find view and a fine verify view from one camera.
Telecentric Measurement Lighting
Choose illumination for telecentric measurement: transmitted backlight vs coaxial vs dark-field, beam-diameter matching, worked examples and the fields to record.
Fiber Connector End-Face Inspection with a 5X APO Zoom Lens
A delivered case: a fiber connector manufacturer images the connector end face with a 0.7-4.5X zoom lens stacked on a 5X APO objective.
Motion Blur in Machine Vision
How to calculate and control motion blur in machine vision: the blur formula, object-side pixel size, acceptable blur in pixels, shutter type and strobe lighting.
Fiber End-Face Inspection Lighting: White vs Yellow
White, yellow or blue for a fiber end face? Compare contrast, diffraction limit and axial color by defect type, plus coaxial and dark-field tables.
