Optical and photonic optical components Test methods for geometric parameters of complex curved surface optical elements

1 Scope

GB/T 47243-2026 is the Chinese national standard covering measuring an aspheric or freeform optical surface - a shape with no axis of symmetry to reference, which is why the fixturing, the sampling of the surface and the fitting of the measured points to the design are the whole of the method. First edition, in force since 1 June 2026. It was issued on 27 February 2026 and has been in force since 1 June 2026, as a first edition. The document is under the responsibility of the China Machinery Industry Federation. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document describes the testing methods for the geometric parameters of complex curved surface optical elements. This document applies to the preparation of composite optical materials such as various optical glass materials, optical crystal materials, silicon carbide ceramic materials, and metallic materials. Measurement of geometric parameters such as profile dimensions, effective aperture, vertex radius of curvature, off-axis amount, eccentricity, and roll angle of complex surface optical elements.
