Through its non-contact, absolute, and material-independent measurement method, white light interferometry delivers consistent results \u2013 even where other optical methods reach their limits.
In combination with Heliotis’ high-speed sensors, it becomes an in-line capable key technology for automated quality control and process control \u2013 from the laboratory to series production.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

WLI measures heights via the optical transit time of light. This physical principle enables constant vertical resolution \u2013 regardless of whether small microchips or large functional surfaces are measured.
The result: consistent accuracy, regardless of lens or working distance. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

In industrial quality control, surfaces of various types meet \u2013 polished, coated, structured, or transparent.
WLI measures reliably on all these materials, as it does not rely on reflectivity, color, or texture. Even highly glossy or transparent surfaces are captured without pre-treatment \u2013 neither powdering nor matting is required. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Thanks to the lock-in pixel technology developed by Heliotis, the interference signal is evaluated directly in the sensor \u2013 up to 1000 times faster than with classical interferometry.
This makes WLI vibration-resistant, fast, and process-capable \u2013 perfect for automated quality control.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Heliotis sensors rely on open industrial interfaces \u2013 from GenICam via EtherCAT\u00ae and PROFINET\u00ae to a comprehensive SDK.
This allows WLI systems to be integrated directly into PLC controls or machine vision PCs \u2013 without proprietary drivers or special solutions.
