Purpose:

23JA desktop measuring projector is a mid-range product with simple structure, convenient use and strong adaptability in our projector series. Using the optical projection method, it is a comprehensive optical measuring instrument that enlarges and projects the contour or surface condition of the test piece on the projection screen, performs contour measurement and comparison measurement, and observes the surface condition. Its main advantages are: the use of a telecentric optical path makes the illumination uniform and eliminates the measurement error caused by the focusing error. The machine is easy to operate and maintain, with high efficiency and strong applicability.

At present, desktop projectors have been widely used in many industries such as standard measurement, clocks and watches, picture tubes, chemical fiber textiles, gemstone bearings, instrument components, papermaking, sugar making and colleges and universities. For example, it is used in length, diameter and process analysis; integrated block solder joints, photolithography, screen printing, hydraulic sealing rings and other occasions that require micro-projection magnification measurement.
