Enhanced Software Tools Power Confocal Scanner Surface Measurement

FocalSpec, specializing in fast surface measurement and on-line testing of challenging materials and shapes, and Digital Surf, global provider of surface analysis software, have teamed up to release FocalSpec Map, a cutting-edge software package bringing a whole new set of tools to users of the FocalSpec’s Line Confocal Imaging (LCI) products.

Customers from a range of industries including mobile electronics, medical devices, plastics and consumer electronics now have the ability to report on surface data in greater depth than was previously possible.

FocalSpec 3D Line Confocal Scanner UULA is an automated optical 3D imaging and metrology system for sub-micron level accurate measurements on any material. The stand-alone system can be utilized in R&D laboratories, smart manufacturing, and quality control applications.

Line Confocal Imaging (LCI) techology used in UULA enables customers to measure 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 can distinguish irregularities of less than one micron. ULLA provides both 3D topography and dimensions and efficiently handles tomographic imaging of transparent objects providing high-precision 2D imaging with extended depth of field.

Analysis tools made available in FocalSpec Map include:

  • Characterization of surface roughness and texture – advanced roughness/waviness filtering techniques – 2D and 3D parameters from Ra to ISO 25178.
  • Surface geometry analysis – including volume of surface structures (bumps, holes), step heights, contour, etc.
  • Quick & easy report generation – analysis routines can be saved as templates and re-applied to batches.
  • SPC analysis of multiple static and dynamic data populations and process capability evaluation.

How LCI works:

LCI Confocal Scanner technology enables 2D and 3D measurement of stationary and moving surfaces at a very high resolution. The LCI sensors use a measurement profile line with 2048 pixels allowing 3D raw measurement data points to be recorded simultaneously.

With a complex optical arrangement, white light emitting from the sensor light source is split into a continuous spectrum with thousands of wavelengths. Each wavelength is focused on a plane with certain distance from the sensor. Depending on how far each of the 2048 surface point from the sensor is, the dominating wavelength for each point is reflected back to the sensor’s receiver.
