Active Optical Perception: How AI Can Control Zoom and Focus
Traditional machine vision fixes the optics, captures one image, and then runs an algorithm.
Build a Motorized Digital Microscope: Zoom, APO, Autofocus
A motorized digital microscope combines a continuous zoom body, a high-NA apochromatic (APO) objective, an industrial camera, and a motorized focus axis so that magnification and focus can be changed without touching the optics. The result is useful for semiconductor, PCB, LCD, FPD, and precision...
Magnification Is Not Resolution: Smallest Visible Feature
Engineers often start a vision project with a magnification number: “I need 20X,” “I want 400X,” or “The defect is 5 µm, so give me 1000X.” Magnification is easy to say, but it is not the right engineering specification. Magnification only tells you how large an object appears on the sensor or mo...
Microscope 400X vs Zoom Lens: Magnification Conversion
400X is an eyepiece-referenced number; a zoom lens states object-side magnification. Here is the full conversion chain, table and self-check.
