Scanning Type Collimated Light Screen Printing Exposure Machine

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
