In order to measure the focal length of a concave and convex lens accurately, theoretical analysis and experimental verification were carried out based on the color digital holographic method, and the measurement difference relative to the nominal value was 1%. The results indicate the digital holographic interferometry is reliable and the same effect as that of lens nominal value reconstruction can be obtained. The result is helpful for digital holographic wavefront reconstruction.
