Method for inspecting an ophthalmic lens using optical coherence tomography

Method for inspecting an ophthalmic lens using Optical Coherence Tomography comprising

• illuminating a defined sample volume including the ophthalmic lens to be inspected with a sample light beam which is provided from a light source having a power of at least 2 mW at a wavelength of 1040 nm to 1080 nm and which does not exceed 5 W, the ophthalmic lens having been manufactured such that it comprises scattering centers embedded in and/or on an anterior surface and in and/or on a posterior surface thereof, respectively, and/or distributed throughout a bulk material being delimited by the anterior surface and the posterior surface of the ophthalmic lens, detecting signals corresponding to an interference pattern resulting from a superposition of back-scattered light from the defined sample volume including the ophthalmic lens to be inspected and a reference light beam provided from the light source,
• analyzing the detected signals and segmenting raw data corresponding to the ophthalmic lens from signals corresponding to the surrounding sample volume, removing refractive effects of the ophthalmic lens and of the surrounding sample volume from the segmented raw data corresponding to the inspected ophthalmic lens in order to obtain geometrical data of the inspected ophthalmic lens, and
• transforming the geometrical data into CAD-readable data representing the inspected ophthalmic lens.
