Abstract
Simple and cost-effective immersion method for freeform optical surface (FFS) measurements is proposed. Method is based on the determination of the borderline curve formed between the contacted immersion liquid and the controlled surface. Proposed method is suitable for measuring polished and rough surfaces, convex and concave freeform, aspheric, spherical surfaces, prisms and another optical and non-optical 3D objects having freeform surface.
