Event Overview
From June 12 to 14, 2026, the 3rd Changchun International Optoelectronic Expo was held in Changchun, bringing together leading companies, research institutes, universities, and industry specialists across optical precision manufacturing and industrial vision inspection.
LightE presented its chromatic confocal displacement sensors and semiconductor precision inspection solutions at the exhibition, joining customers, partners, and industry peers to discuss emerging applications and technology trends.
Highlights at the Booth
As a high-tech company focused on precision optical measurement, LightE highlighted independently developed chromatic confocal sensors and high-precision inspection solutions for optoelectronics, semiconductor manufacturing, and other advanced industries.
The booth drew strong interest from professional visitors. Sales engineers and technical specialists introduced product performance, measurement principles, and application cases in detail, helping visitors understand how non-contact optical measurement can improve process stability and yield.
Application Value
For optical communication, semiconductor, and precision manufacturing scenarios, measurement systems must deliver high accuracy, high stability, and strong adaptability to complex materials. LightE demonstrated how chromatic confocal technology supports micron- and sub-micron-level displacement, thickness, flatness, and profile measurement without contacting the target surface.
Through on-site discussions, LightE further strengthened communication with upstream and downstream partners and gained valuable insight into new inspection requirements from the Northeast China optoelectronics industry cluster.
Looking Ahead
LightE will continue to deepen its work in precision optical sensing, promote the industrial application of domestically developed high-end measurement technology, and provide reliable inspection components and solutions for advanced manufacturing customers.
