More precise, better, more economical – nothing less will do. Machine solutions by ACSYS are characterized by maximum exactness, precision and repeatability. Laser digitizing is based on the technology of conoscopic holography and allows the creation of extremely precise digital 3D data of a wide range of very different surfaces, plaster models, dies or actual coins and medals.
The resulting 3D file can be used for production and reproduction and can easily be processed in the CAD software. The advantages of this contact-free method are high speed and small measuring grid distances. Perfect accuracy of 2 µm can be achieved with the replaceable lens system. Conoscopic holography is a patented process and offers the greatest precision and repeatable accuracy over a wide range of applications.
The image on the right shows the design of the ACSYS laser scanner. The laser beam is used for creating a light dot on the object that is to be measured. Part of the light, which is reflected from this light dot, is captured by the sensor's lens and falls on the conoscopic crystal. There the incoming light rays are initially separated into partial rays, before being reunited into the original rays after their exit from the crystal. This creates an interference pattern, which is captured using a CCD sensor and then electronically evaluated.
