Inspect the insides of medical plastic parts

Medical parts are often transparent and translucent which can be tricky for optical measurements. At the same time, medical components require confident evaluation of tiny channels and inner structures. A scanner like ZEISS METROTOM 1, which acquires data via X-ray images, captures the complete inside and outside geometry non-destructively and with high precision.

Scanning small parts with GOM Scan 1 and ATOS Q

From plastics to electronics and consumer goods, small parts are everywhere. Their geometries range from simple to complex with fine structures and tiny holes, each with specific measurement requirements. With the 3D scanners GOM Scan 1 and ATOS Q, scanning small parts is easy.
