    • The invention proposes a method and a system for identification of a given geometrical feature of an optical component chosen within the list consisting of an ophthalmic lens or a semi-finished lens blank for ophthalmic lens. Said method comprises the following steps consisting of: -providing (32) the optical component (12) made of an organic material with the proviso that said material can emit light at an emission wavelength λ e when being lighten at an illumination wavelength λ i which is different from the emission wavelength λ e ; -illuminating (34, 74) a surface (16, 64) of the optical component with an incident light beam comprising at least light at the illumination wavelength but devoid from the light at the emission wavelength; -collecting (36, 76) light emitted at the emission wavelength by the illuminated surface of the optical component to build an image of the said surface; and -processing (38) said image by implementing computer means and applying a metrics to compare the image with reference data that are specific to the given geometrical feature and providing an identification output of said given geometrical feature.
    • 本发明提出了一种用于识别在由用于眼科镜片的眼科镜片或半成品镜片坯料组成的列表内选择的光学部件的给定几何特征的方法和系统。 所述方法包括以下步骤: - 提供(32)由有机材料制成的光学部件(12),条件是当在照射波长不同的照明波长下发光时,所述材料可以在发射波长兰德发光 从发射波长lambdae; 以光照射波长但至少不含光的入射光束至少包含光照射部件的表面(16,64)的方式(34,74); - 通过所述光学部件的被照射表面在所述发射波长处发射的光(36,76),以构建所述表面的图像; 并通过实施计算机装置并且应用度量来比较图像与特定于给定几何特征的参考数据并提供所述给定几何特征的识别输出的处理(38)所述图像。
