With Continuous Confocal, the company has developed a confocal technique that utilizes a continuous z-axis scan. The acquisition speed is comparable to Focus Variation and is roughly three times faster than Sensofar's existing Confocal approach while maintaining a comparable repeatability and accuracy. According to the exhibitors, the solution is ideal for QC tasks where speed is a key factor and is essential for reducing acquisition times for large-area and extensive z-axis scans. Confocal Fusion is another new measurement technique from the developers. It is claimed to combine the best from Sensofar's Confocal and Focus Variation techniques by using a unique smart algorithm that yields the most reliable data from a single scan. Where neither Confocal nor Focus Variation can provide ideal results, Confocal Fusion reportedly surpasses the limitations of both techniques to provide high-quality measurements over spatially highly varying surfaces. It is seen as excellent for highly complex or technical surfaces exhibiting both steep rough and steep smooth areas, and where a traditional confocal approach alone would fail to capture the surface adequately. Both measurement technologies are said to conform to ISO 25178 requirements.
Detecting complex surface geometries
Sensofar Metrology has developed two new measuring technology features that are suitable for complex surface geometries and for routine surface measurements in research and development or in industrial environments.
