Simple, fast, and affordable optical measurement of reflective surfaces at nanometric precision
Wyse Light invented coaxial deflectometry to make reliable high accuracy optical 3D measurement of the shape of reflective surfaces easy and affordable. Flats, spheres, aspheres, off-axis parabolas, cylinders, prims, freeforms! Same setup, same simplicity, same speed, same cost. Only one system to measure them all.
Shorten your production cycle of precision optics, solve the metrology expert shortage/bottleneck, relieve stress on your key experts with our simple to use, fast, and affordable optical metrology instrument for nanometric accuracy full-frame measurement of the shape of reflective surfaces.
Coaxial deflectometry is not sensitive to vibrations or temperature so it naturally operates in the metrology lab and the shop floor as well.
Simplicity
A push-button instrument with no need of fine alignments, reference surface not CGH. To lift the fundamental shape ambiguity associated with deflectometry, we have invented and patented coaxial deflectometry, an innovative implementation that yields nanometric precision that everybody can use.
Performance
Middle and high spatial frequencies are measured with an accuracy better than 3 nm, and the low frequencies with a typical 15 nm accuracy.
And it is fast. A repeat measurement takes 2mn. The whole system setup takes less than 30mn. It is easily transportable (measurement unit weight only 6 kg/12 pounds).
Robustness
Integrated calibration bench for camera/lens sight rays characterization. Self-calibrating: camera and screen positions are numerically fine-tuned for each measurement. Low sensitivity to parasitic vibrations: no special concrete slab, no damped optical table required! Measurement possible even in the shop close to the machines with no negative impact on accuracy.
Nanometric accuracy with our easily deployable off-the-shelf table top setup
WYSE light Ray Master is composed of a measurement unit and a display screen that can be used on a regular table top desk, deflectometry being basically insensitive to vibrations. Now you can measure anywhere! And yes, you can new have nanometric accuracy on an office desk like this. We even made demonstrations on our booth at OPIE in Yokohama this Spring 2025 on a folding table.
Comparative results with the best high-end instruments
We have made many measurements of very different samples, and were able to compare our results to the ones obtained by instruments like Taylor&Hobson Luphoscan, DUI Nanomefos, and Zygo interferometers. As an example, on the left, you can see an example of comparative measurements. We have plenty now with differents parts from plano to freeforms, including spheres, aspheres, parabolas, prisms, cylinders, toroidal… With the very same setup that we sell, the largest part that we measured so far was a 800x300mm concave freeform mirror. The smallest was a 15mm diameter lens. Comparisons are with interferometric measurements and CMM measurements. Sometimes we could even measure parts that were not measurable with other commercial systems by their owners (in reference to a very famous research lab in the US. Our collaboration being under NDA we can’t give more information).
Classic deflectometry vs coaxial deflectometry (patented)
Deflectometry is a technique that has long been known in the field of optical metrology of reflective objects. It is based on the analysis of the image of periodic patterns reflected by the object under examination, that carries in some way information about the object shape.
A well know limitation of deflectometry for shape measurement is a fundamental ambiguity: there is an infinite number of solutions for the shape, depending on the unknown camera-to-object distance. WYSE light patented technology, coaxial deflectometry, overcomes this limitation.
We are a Luminate portfolio company. Wyse Light has been selected in March 2025 to integrate the Nextcorps Luminate startups accelerator, the first and largest startups accelerator dedicated to the optics photonics sector.
