Precision Optics Manufacturing

OTéO know-how extands on lapping, polishing and measurement of optics.

Coatings are manufactured through professional partnership following your specifications.

We manufacture from prototype to volume.

Manufacturing assemblies are done using glue, wax or molecular adherence, depends on your product.

Our experienced optics know-how allows us to answer to your optics projects.
