WebFeb 4, 2024 · A beam of light from the light source is passed thru the condenser lens (C) and Projection lens (P) and fall on the Screen. the workpiece will be placed in between the light source and condenser lens. … WebProfile projectors (optical comparators) are a type of optical measuring instrument. The measurement principle is similar to that of optical microscopes. The target is placed on the stage, and a light is shined on the target from underneath. This causes the target's profile, or shadow, to be projected on the screen. A telecentric optical system ...

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.
