Principle of optical projection grinder

1, the optical projection screen is imaged as a positive image, which conforms to the optical measurement habit;

2. Different perspective lighting at high and low levels can meet the measurement requirements of different workpieces;

3. The aspheric spotlight illumination system makes the field of view of the projection screen bright and symmetrical, which reduces the measurement error and ensures the accuracy;

4. Adopt imported Philips long-life tungsten halogen lamps to meet the needs of long-term use;

5. The axial flow fan radiates heat in both directions, providing super heat dissipation capacity;

6. Equipped with DC-3000 multifunctional digital display meter and micro printer.
