Machine Vision Inspection Application Cases: Complete Index
Index of POMEAS machine vision application cases by industry: fiber optics, electronics and semiconductors, medical parts, and multi-product integration, each with the optics and lighting used.
Machine Vision Optics Selection Guides: Complete Index
Index of every POMEAS selection guide: telecentric, zoom and FA lenses, sensor matching, lighting choice and depth of field, grouped by the question you are trying to answer.
FOV Calculator: Field of View and Pixel Size from Sensor and Magnification
Interactive FOV and pixel-size calculator from sensor size, magnification and resolution, plus a working-distance mode, the three formulas behind it and worked examples.
PCB AOI Optical Selection: Pixel Size, Lens Type, Working Distance and Lighting
A four-step optical selection for PCB AOI: pixel size from the smallest feature, lens type against height variation, working distance as machine budget, and lighting geometry for solder joints.
Working Distance vs Depth of Field in Machine Vision: What Each One Controls
Working distance decides where the lens sits; depth of field decides how much the part may move. What each one controls, how they trade off, and a selection sequence that avoids the trap.
