About us
Wyse Light specializes in the development of high-precision optical measurement instruments based on the method developed and patented by Pr Yves Surrel and called coaxial deflectometry. Wyse Light provides simple, fast, and reliable products for measuring reflective surfaces with nanometric accuracy. It is equally effective for mirrors and lenses, whatever their shapes, making Wyse Light an innovative technological leader in the field of optical metrology on a global scale.
Our Story
Wyse Light was created in March 2021 by Yves Surrel, PhD, Ecole Normale Supérieure graduate, expert in optical metrology with a rich academic and industrial background. For Yves Surrel, this project is the culmination of a career as a researcher, both in the public sector (as a teacher-researcher at the École des mines de Saint-Étienne and then as professor of instrumentation at the Conservatoire national des arts et métiers in Paris and at the National Institute of Metrology, INM – now attached to LNE) and in the private sector (as director of research and development in the company Visuol Technologies in Metz, France). Yves Surrel has dedicated his professional career to providing solutions to optical metrology problems. In particular, he has worked extensively on the technique of deflectometry.
Deflectometry challenges…
Deflectometry is a non-contact optical measurement technique that determines the shape of reflective surfaces by analyzing how known patterns (like fringes) are distorted when reflected by the surface. Deflectometry is already being used for surface quality control and precision measurement applications.
Interferometry has been the reference technique for high accuracy measurement of the shape of reflective surfaces. But deflectometry has several decisive advantages over interferometry:
- ease of implementation
- independence from environmental conditions like vibrations, temperature
- cost price
- direct full frame measurement
- does not require fine alignment nor reference surface
But using deflectometry for high accuracy measurement, that is in terms of nanometers which is what you can achieve with interferometry, it requires to have a perfect knowledge of your measurement system. And that is so challenging that it had not been achieved so far except by a few top precision optics manufacturing companies and labs that keep it secret since it has been so long and costly to develop. They consider it as a strategic advantage over the competition.
…overcome with innovative patented technology
Thanks to the unfailing support of the French Public Bank of Investment, Yves Surrel has succeeded in developing and patenting a measurement method based on deflectometry that solves its very complex difficulties. He called this method coaxial deflectometry, based on its principle and mode of operation. He and his team has also developed a measuring device that implements this method. The results of comparative measurements made against very expensive devices on the market ($100K>1M) based on interferometry show equivalent or even better performance (ability to measure freeforms more efficiently). This device also has the advantages of being up to 15 times simpler to implement and use, space-saving, faster and more affordable than interferometry and CMM. High-end metrology to measure the shape of reflective surfaces is now accessible to all companies and labs for considerably lower capex and opex.
Our mission
Wyse Light’s mission is to support customers that need high precision optical metrology devices worldwide to measure reflective surfaces of mirrors and lenses, whatever their shapes (flats, spheres, aspheres, parabolas, toroidal, cylinder, freeforms…), by providing them with simple, fast, reliable, and accurate products based on coaxial deflectometry.
