1. An insert coaxial thermal radiation image evaluating system, comprising:
a cage support;
a first lens;
a first cage movable frame movably disposed at the cage support and connected to the first lens;
a light detector;
a second cage movable frame movably disposed at the cage support and connected to the light detector; and
a cage holder connected to the cage support to fix the cage support to an optical substrate, wherein the first cage movable frame is movably disposed in the cage holder,
wherein the first lens and a second lens of a metal additive manufacturing system together form a structure of conjugate foci, such that a thermal radiation generated from a high-power infrared laser irradiation zone forms according to a fixed ratio an image captured by the light detector.
