EVT’s EyeVision software now supports the FocalSpec 3D Line Confocal Scanner UULA.
This is an automated, stand-alone optical 3D imaging and metrology system for submicron level accurate measurements on any material.
Line Confocal Imaging (LCI) technology used in UULA enables customers to model the most demanding surfaces and shapes, even mirror-like, curved and transparent objects. UULA’s LCI sensor detects millions of 3D points per second, and it can distinguish irregularities of less than one micron. The UULA consists of a light source and a CMOS array which are arranged in an angle to each other.
The EyeVision software can carry out different measurements on the captured point cloud and profile. The Metrology command set as well as the 3D Profile commands can be applied to the scans. The Profile Match command for example can compare previously configured profiles with the scanned profile and therefore can detect defect profiles.
The UULA is the solution for a number of challenges, including for devices that are becoming smaller and thinner and the materials and shapes designed more complex. In addition, it has been difficult carrying out sufficiently accurate measuring during actual production, resulting in costly halts.
