Profile Projectors - Optical Comparators

Application

The Profile Projector - Optical Comparator is a important measuring instrument used for accurate measurement and comparison tasks. It consists of a projection lens, a projection box, the main body, and a working table, enabling users to magnify and inspect small or intricate parts with precision. This device is essential in industries such as mechanical manufacturing, instrumentation, molds, tools, and light industry, as well as in measurement rooms and workshops associated with factories and mines, particularly in the electronic clock and watch sectors.

Profile Projectors - Optical Comparators

Profile Projectors - Optical Comparators support repeatable, non-contact dimensional checks by projecting magnified part profiles for fast pass/fail decisions. Standardized fixturing and lighting help maintain a consistent sample prep workflow across QC and R&D. Use the table below to compare the best option for your lab.
