Wyse Light unveils portable RayMaster10 for optics | Luminate Profile

In industries like aerospace, medical imaging, and augmented reality, manufacturers rely on highly accurate optical components. But measuring the shape and surface quality of these parts, especially mirrors and lenses with unusual shapes, has traditionally required expensive equipment, controlled environments, and highly trained specialists.

Wyse Light has developed a compact, tabletop device that uses a novel optical technique called coaxial deflectometry. Coaxial deflectometry was pioneered by founder and longtime metrology researcher Dr. Yves Surrel, to measure the shape of reflective surfaces with nanometer precision while replacing bulky and expensive systems. The method offers manufacturers a faster, easier, and more cost-effective way to inspect complex optical components.

“Our approach removes many of the limitations that come with traditional tools,” said Eric Romestant, general manager of Wyse Light. “It’s accessible, efficient, and doesn’t require an optics expert to operate.”

The device is also highly portable, weighing just 6 kilograms, and doesn’t require vibration-free tables or climate control. It can be used directly on the production floor or in a workshop, which is especially valuable for companies needing in-process metrology.

The core technology was developed by Dr. Surrel, who spent much of his career working on surface measurement. While deflectometry had previously been used in industries like automotive manufacturing, the method never reached the accuracy needed for optical applications. Surrel’s breakthrough helped overcome this limitation.

“Thanks to Yves’s work, we were able to take an underutilized method and transform it into a high-performance tool for precision optics,” said Romestant.

Removing barriers for optical manufacturers

With its simple setup and broad compatibility, the RayMaster10 is helping optics manufacturers streamline their workflows and reduce dependency on third-party labs or complex, specialized equipment. It can measure optical parts ranging from 20 millimeters to over 800 millimeters wide regardless of their shape (plane, sphere, asphere, cylinder, tore, parabola, freeform …) — all using the same device with a speed and accuracy competitive with interferometers but without their costly and numerous accessories. New RayMaster models will be developed to measure smaller and larger optics, in one shot too, like the RayMaster10.

“The versatility is what excites our customers,” said Romestant. “They can measure more types of optics in just a few minutes without retooling or adding expensive accessories.”

In addition to shape measurement, the system’s software can detect surface defects and visualize results in 3D, giving users deeper insight into part quality. This capability is especially relevant as industries increasingly adopt miniaturized, freeform, and high-tolerance optical designs.

Interest in the system is growing as more companies face pressure to speed up development cycles while maintaining quality standards. Wyse Light is positioning itself as a metrology partner that can grow alongside its customers.

Establishing a foothold in the U.S. optics industry

Wyse Light joined the Luminate accelerator in 2025 as part of a strategic effort to expand into the U.S. market. Through the program, the company gained access to industry mentors and key players in optics manufacturing.

“Luminate has been instrumental in helping us navigate the U.S. market,” said Romestant. “It connected us with leading optics companies and provided guidance on both business development and investor outreach.”

The company is currently raising €1 million to support business expansion, hiring, and the upcoming launch of the RayMaster10 M4—a smaller, more advanced version of its original system. The new model is being designed to reduce setup time and system footprint while offering upgraded software, improved nanometer-level accuracy, and greater reliability for high-throughput manufacturing. It will also feature enhanced surface defect analysis and a guided interface that makes precision measurement easier, even for first-time users.4833

If awarded follow-on funding at Luminate Finals, Wyse Light plans to use the investment to scale manufacturing, expand its sales team within three states, and further develop its technology to support both large and small optics, while continuing to improve system performance and ease of use.

“Wyse Light aims to democratize access to high-quality optical metrology, enabling superior performance, miniaturization, and affordability across industries,” said Romestant.

The companies of Luminate cohort 8 will compete for $2 million in follow-on funding at Luminate Finals 2025 on October 22. The program is funded by Empire State Development’s Finger Lakes Forward Upstate Revitalization Initiative. For more information about the Luminate accelerator and Finals 2025, visit luminate.org.
