Comparators don't get no respect, or at least they may be underrated and under utilized. The reason may simply be because its more famous sibling, the op amp, usually gets the spotlight. “In large ...
Comparators have an op-amp front end and a digital back end that operates like a gate. The comparator output stage may be an open collector transistor, so it often connects to the logic supply through ...
Simple optics display the part upside down and backwards on the glass screen. Corrected optics display the part right side up and backwards. Fully corrected optics yield an image identical to the part ...
Used for a wide range of dimensional inspection purposes, optical comparators measure the dimensions and geometry of a sample through a projected image. The mechanical system within the operator ...
Inspecting with Optical Comparators provides an overview of the optical comparator, which uses optics to project an enlarged, two-dimensional shadow of a part onto a glass screen for measurement of ...
