Sensofar Metrology has announced two new measurement technology features as well as a hardware add-on for its existing S line 3-in-1 surface metrology systems.
With Continuous Confocal, Sensofar has developed a confocal technique that utilizes a continuous z-axis scan. Acquisition speed is comparable to focus variation, and is roughly 3x faster than Sensofar’s own confocal approach while maintaining comparable repeatability and accuracy.
Confocal Fusion refers to another new and proprietary measurement technique that draws the best out of 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 or focus variation can provide ideal results, Confocal Fusion provides high-quality measurements over spatially highly varying surfaces. It is ideal 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 Continuous Confocal and Confocal Fusion measurements still conform to ISO 25178 requirements.
Both these new measurement technologies draw on Sensofar’s particular utilisation of a microdisplay in their 3-in-1 3D surface metrology systems to provide confocal, interferometric and focus variation approaches.
