Optical components

Winlight System offers proven expertise in the manufacture of high-precision plano, spherical and aspherical (on-axis, off-axis or free-form) optical components, as well as X-ray mirrors.


By combining our opto-mechanical and electronic skills, we make fully-qualified optronic (electro-optical) products on request.

Calibration & test benches

Winlight System designs calibration and test benches (optics and optronics) capable of aligning, checking and qualifying the optical and photonic aspects of high-performance systems.

Spectroscopy & imaging systems

Winlight System contributes to the development of a number of instruments for large telescopes (VLT, ELT, Keck, Gemini, Subaru, etc.)

Instrumentation for plasma experiments

Winlight System designs and builds x-ray microscopes used in plasma diagnostics for large scientific facilities.


Founded in 2001, Winlight System is a French company specialized in the design and construction of high-performance optical components, subassemblies and systems, all compatible with the most demanding environments.

Winlight System primarily operates in the space, defense, synchrotron and astronomy sectors. Its technical expertise is recognized worldwide, spanning the design and construction of optical components, complex subassemblies and high-precision test and calibration benches.

The company’s expertise encompasses all steps in the design, development and production of optical systems, including lenses, mirrors and other unique components. In particular, Winlight System deploys proprietary polishing, assembly and testing technologies.

Winlight System was acquired by Bertin Technologies, a CNIM company, in 2017. This link-up bolsters its range of optical and mechanical systems for big science facilities, including synchrotrons, telescopes and research reactors, as well as for major space and defense programs. ISO 9001:2015 certified, Winlight System is committed to providing the highest quality to its customers in Europe, Asia and the United States.
