1. Parallel parabolic rays (reflexive, non-degradative in energy) are applied, whose performance is better than using Fresnel lens which is refractive and degradative. The resolution is 25 pm.
2. Scanning exposure technique is applied, and the optical uniformity of the exposed surface reaches more than 98%.
3. The lamps are powered by digital direct current with continuous adjustable power rate and frequency, which is able to prolong the lifespan of the lamps and save about 60% of the energy consumption comparing with traditional transformer power supply.
4. The scanning range can be adjusted according to the size of the objects, resulting in high efficiency.
5. The machine is equipped with hydro cooling systems to cool the glass surface, avoiding from unexpected size changing of the objects due to high temperature.
6. Equipped with a 7-inch color touch screen for display and control.
7. With memory capacity of 80 groups of setting data.
8. Designed for high vacuity, resulting in minimal error between the scanned object and the scanning graph.
9. The vacuity can be controlled, enabling a customized size of the scanning graph.
10. Cold UV lamp is optional.
