Summary: Magnifying
and measuring part profiles.
Optical
comparators are measuring instruments that project a magnified image of a
part's profile onto a screen. This allows for precise measurement and
inspection of its dimensions and shapes. Here's a bit more detail:
* **Function:**
Optical comparators use a system of lenses and mirrors to create a shadow image
of the workpiece, which is then compared to a master outline or scale on the
screen.
* **Use:** They are
commonly used in manufacturing for quality control to inspect parts for
accuracy, detect defects, and verify dimensions, especially for parts with
complex or small features that are difficult to measure with other tools.
* **Advantages:** Optical comparators offer high magnification, non-contact measurement (preventing damage to delicate parts), and the ability to inspect features that are hard to reach.
