NACTUS is a lighting module made of different optics  NACTUS is the first and unique Optical System using different optics with different geometries, combined and set together in the SAME SYSTEM. The core optics forming NACTUS are basically 6.  By acting on the optics while each module is injected, it is virtually possible to customize any application. NACTUS is a lighting module made of different optics, that can be used as a real single lens. The concept is simple: NACTUS maximizes the lighting beam through its optics, so creating a lighting beam of a certain power and fully configurable for the final application considered.
