The global White Light Interferometry (WLI) market size is predicted to grow from US$ 223 million in 2025 to US$ 290 million in 2031; it is expected to grow at a CAGR of 4.5% from 2025 to 2031.
The white light interferometer uses the white light interference technology as the principle. The light emitted by the light source is collimated by a beam splitter and split into two beams after being expanded and collimated. One beam is reflected by the measured surface, and the other beam is reflected by the reference mirror. Eventually convergence and interference occur, the microscope converts the topographical features of the measured surface into interference fringe signals, and measures the three-dimensional topography of the surface by measuring changes in the interference fringe.
The global white light interferometry (WLI) market has a high degree of concentration. Core manufacturers include AMETEK, Nikon and BRUKER. The top three manufacturers account for more than 50% of the market share. The market is dominated by a few leading companies. These companies have significant competitive advantages in high-precision measurement and surface analysis with technological innovation and mature market layout. In terms of geographical distribution, North America and Europe are the main production areas, with a combined share of more than 65%. The US market is the largest, accounting for 31% of the global market, followed by Europe and China, accounting for 27% and 18% respectively, indicating that these regions have strong demand in high-end manufacturing and precision testing.
In terms of product types, white light interferometers with 3-4 lenses occupy the largest market share, reaching 63%, fully demonstrating that multi-lens systems are widely used in the market due to their higher measurement accuracy and flexibility. Multi-lens technology can provide better solutions for the detection of complex surfaces and micro-nano structures, so it has been widely adopted in industries with extremely high precision requirements such as electronics and semiconductors. With the development of technology, multi-lens white light interferometers are expected to be further optimized to adapt to more complex measurement needs.
