Laser performance on Water Screen system is using laser emitter to emit beam of laser light onto water film. This film is a transparent one that made by high-pressure water pump and tailor-made occurring implement, which make the water spray from the bottom up with high speed. Through a process of atomization, a fan-shaped water screen is formed. High-colored laser light with various designs programmed by controlling system irradiates onto glittering and translucent water screen, which form a gorgeous and fantastic effect.
