1. An optical characteristic measuring apparatus for measuring a characteristic of a light transmitting objective, said apparatus comprising:

  • an incident light supplying element for supplying incident light to said objective;

    a waveform distortion measuring element for measuring a waveform distortion degree of the light transmitted from said objective; and

    an optical output adjusting element for adjusting an output of the incident light prior to supplying the incident light to the objective so that (i) the output of the incident light, after being adjusted by the optical output adjusting element, has a range of wavelengths wider than that of the input of the incident light which has not been adjusted by the optical output adjusting element yet, and wider than that of the output of the incident light if assuming that the incident light is directly supplied to the objective without being adjusted by the optical output adjusting element, and (ii) said waveform distortion degree measured by said waveform distortion measuring element falls within a predetermined range.
