WebJun 22, 2024 · The optical scale is usually made from glass or plastic, sometimes from aluminum. Optical technology allows linear measurements with the greatest accuracy and high resolution. However, pollution or solid particles in a gap between measuring surface and sensor as well as mechanical shocks and vibration can significantly affect the …

Optical Comparators: What are They? How do they work?

WebAt first, the only way to measure with an optical comparator was by comparison--hence its name. Part images could be compared to rulers and protractors placed across the screen. For example, a measurement of 1/32 in. on-screen equates to 0.001 in. on the part when using a 31.25X lens. WebA comparator circuit compares two voltages and outputs either a 1 (the voltage at the plus side) or a 0 (the voltage at the negative side) to indicate which is larger. Comparators are often used, for example, to check … granite mountain trailhead scottsdale

Optical Comparators: What are They? How do they work?

WebThe basic concept of an optical comparator for quality control use is to take that idea of the overhead projector and package it all up inside a box so that the optical distance between the part and the screen is fixed, known and can be calibrated.
