Cure depth of photo‐polymerized gels is theoretically analyzed. The critical point in a frontally photo‐polymerized sample is determined by the critical degree of polymerization, which is derived by the concentration ratio of monomer and initiator. While the total polymer depth or gel depth weighed by the monomer conversion depends on both radiation energy and light intensity, the averaged cure depth around the critical point depends on radiation energy only. The profile is consistent with experimental results. This is a practical formulation of the cure depth of photo‐polymerized gels without any empirical parameter.
