V-Groove and Fiber Array (FAU) End-Face Inspection: Telecentric and Microscope Imaging Options
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 Many Stations Do You Need?
How to calculate inline measurement cycle time and station count: takt time vs cycle time, the per-part time budget, availability, worked examples for 2,000 parts per hour, and six common errors.
Machine Vision Light Source Colour: Wavelength Selection and Photolithography Yellow Light
How to choose machine vision light source colour and wavelength: same-colour vs complementary light, monochrome and colour camera pairing, and how to turn a photolithography yellow-light requirement into a testable specification.
Machine Vision Light Source Selection: Point, Ring, Telecentric Parallel and Coaxial
How to choose a machine vision light source: reflected vs transmitted light, and point, ring, telecentric parallel and coaxial types, with published POMEAS specifications for beam diameter, working distance, wavelength and controller.
Motorized Zoom Lens for AOI: Magnification Change Without Downtime
AOI needs a wide find view and a fine verify view from one camera. How motorized zoom lenses change magnification between recipes, and how magnification repeatability is verified on the line.
Telecentric Measurement Lighting: Backlight vs Coaxial vs Dark-Field
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 Case: Zoom Lens with 5X APO Objective and Yellow Coaxial Light
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. Total magnification about 12.4X, measured working distance 65 mm, yellow coaxial illumination. Includes the mounting drawing and the selection takeaways.
Motion Blur in Machine Vision: Exposure Time and Conveyor Speed
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.
