Abstract: Method and device for accurately measuring focal lengths of a dioptric system, in particular one which is spherical, aspherical, cylindrical, toric or more generally arbitrary. The invention relates to a method and a device making it possible to measure focal lengths of a dioptric system without carrying out imaging. The device associated with the method uses the incident wave emanating from a light source (1 & 2), spatially calibrated (3), a periodic test pattern (4) with suitable transmission profile, and a beam analyser (8) linked to a computer (9) which assesses both the periodic modulation and the radius of curvature of the wave emerging from the system to be measured (6). The latter is placed on a platform (5) equipped with an adjustable diaphragm (7). The invention ensures measurements compatible with the ISO standards 11979-2 and is suitable for measuring focal lengths for metrological applications in the fields of ophthalmology and scientific and industrial instrumention.
