As k-Space Associates, Inc. continues to expand their industrial metrology product line, they are excited to introduce the newest addition, the kSA XRF (X-ray fluorescence). This metrology system measures the layer thickness of metal films and dielectric films that are too thin for reliable optical measurements. It provides inline measurements for films on many substrates and applications, including glass and solar panels.

The system is comprised of an X-ray tube with a high voltage generator and an X-ray detector system. The system identifies the spectral peaks for the X-ray emission spectrum and collects the peak intensities for further processing. The tool measures the appropriate atomic species based on the customer’s coating formula and measurement needs. k-Space can integrate this tool into existing QC systems and add alarms to flag thickness issues in real-time.

Darryl Barlett, CEO of k-Space, stated, “We developed a solution for one of our customers who needed to measure the thickness of coating layers that were less than 100 nm thick. Our team of physicists and engineers took the production environment into account and designed this tool for inline measurement that provides real-time results. Because there is a growing need for this type of tool, k-Space decided to make it a regular offering in our industrial product line. We think that it will be beneficial to any business that needs to measure coatings that are outside of the reliable optical thickness range.”
