Precision metrology for diffractive optics
Optical components such as Fresnel lenses and aspheres with diffractive surface structures pose unique challenges for metrology. Their complex geometries often cannot be accurately measured using conventional interferometric or tactile methods. This is where DIOPTIC excels: we design computer-generated holograms (CGHs) precisely tailored to these diffractive surfaces, enabling highly accurate form measurements even for the…
