It is well known that metrology is as important as polishing for precision optics manufacturing. Safran Reosc has naturally built up through the years a unique skill in designing and developing precision optical metrology set-up for all size and shape of optics.
The control of the residual defect along all the spatial frequencies is mandatory in order to ensure high imaging resolution, low flare and low losses by diffusion from the various components of the optical system.
Concave asphere testing
Safran Reosc has set-up a universal test bench specialized on concave spherical and aspherical optics testing at their center of curvature, directly or through Computer Generated Hologram (CGH).
The set-up is optimized for rapid optics adjustment and interchange in order to rapidly and efficiently feed the optical manufacturing team with accurate optical metrology data.
