Abstract:
    This invention discloses one high reflection rate lens measurement method, which comprises the following steps: a, two same concaved high reflected concaved surface form direct chamber and to send continuous laser into stable resonance chamber or co focus chamber and when light chamber output signal range value is larger then set valve value, it closes laser beam to get direct chamber annealing time by index annealing signal matching to get chamber reflection rate; b, keeping chamber length unchanged and adding high reflection lens to form fold chamber between two blocks and when the output signal range value is larger than valve value, it closes laser beam to get fold chamber annealing time to compute test lens reflection rate.
