FS-4  It is the innovation of CR-TEC for double directions rotating two dimensional grating laser that leads a new trend of grating effect
Adopting the grating element with equal energy level, wide scattering angle and uniform power beam, By controlling two rotating motors’ speed, frequency of back and forth shaking which can make the effect of glowworm, laser flower, laser bubble, laser line, laser explosion, laser lightning, laser star and cloud image etc. Built-in 3kinds of DISCO effects, soft, comprehensive model, with IR wireless remote control,control as your will,. Suiting for box, family dinner room, small scale party, club etc.  to use it as the background image.

Microstep subdivision technique,smooth and stable image
Using the super singlechip to hardware PWM refining disposure, 32 subdivision motor, making laser show smooth and stable, approachoing the effect of optical scanner's light beam scanning. Subdisvison treatment improves the stepping motor's dynamic function which makes the laser image more smooth and stable.

PWM refinement treatment
Adopting super singlechip to get the subdivision disposure of hardware PWM, well-designed  32 subdivision of driving circuit, to make program smooth and stable same as the effect of optical scanner.

Grating switching,, perfect combination of scanning device and grating
Light beam scanning laser light, with grating switching, injecting new energy. Making the scanning image on full sky.  Rotating big grating, 50mm diameter, 300 lines in well-distributed, making the image move in wide angle.  With control of grating’s rotating speed, the new visual impact, it can be used as background effect.

Three DMX models
DMX has three kinds of different scene pass, giving you the easy control and edit.
