LMI Technologies of Vancouver announced the acquisition of FocalSpec, an innovative optical metrology company based in Finland that designs and manufactures patented line confocal imaging (LCI) products. LMI’s parent company – the TKH group – will acquire hundred percent of the shares of FocalSpec. The company will be integrated into the LMI group of companies and the LCI products will continue to be sold under the FocalSpec product brand.

FocalSpec LCI sensors leverage a unique optical method based on lateral chromatic confocal scanning that is mounted off-axis to simultaneously capture 3D topography (surface geometry), 2D intensity (surface contrast), and 3D tomography (scanning multiple layers beneath a transparent surface) at sampling speeds up to 27 million data points per second. No other vision solution on the market combines this level of speed, precision, and multimodal, multilayer imaging capability.

Off-axis, line confocal design uses a white light source, and reflection of “orange” and “blue” wavelengths from the high and low points of an object (top and bottom respectively) are mapped to specific pixels on a camera. (Click for larger version; source: FocalSpec)

The acquisition of FocalSpec expands LMI Technologies’ smart sensor portfolio of laser profilers and structured light snapshots with patented confocal technologies. Together, our scanning and inspection solutions lead the industry in solving challenging applications across a variety of markets such as consumer electronics, battery, pharma, semiconductor, and medical.

“Line confocal sensors offer a leap in technological performance for scanning opaque, transparent and curved materials, such as hybrid glass assemblies common in cell phone manufacturing. By combining this game changing optical approach with our proven Gocator inspection software and volume manufacturing know-how, customers will be able to solve challenging inline metrology applications at a price/performance and ease of use never seen in the market today,” said Terry Arden, CEO, LMI Technologies.

Said Sauli Törmälä, chairman of FocalSpec: “The addition of LCI technology to the 3D product portfolio of LMI Technologies builds a highly complementary set of solutions for metrology applications in critical assembly processes. Along with their leading inspection software, we believe FocalSpec and LMI will be a power house of metrology in the years to come and we look forward to joining forces.”

The FocalSpec unit in Oulu, Finland will act as the LMI competence center for the LCI technology globally and the current activities will continue, focused on product development and operations. The development work will gain additional resources and platforms from the LMI Group’s existing metrology operations. FocalSpec’s sales organization will be strengthened considerably as the products will get access to the LMI group’s extensive sales network globally. (Sources: LMI / FocalSpec)
