    摘要: An apparatus for measuring a light absorpiton characteristic of a thin film is provided.The apparatus comprises (1) a liquid container containing a liquid on which surface a thin film is to be spread, (2) exciting light source for supplying an exciting light to be projected from below the liquid surface on to a measurement site of the thin film spread on the liquid surface, at such an incident angle that the exciting light reflects totally at the liquid surface, (3) a chopper for converting the exciting light into an intermittent exciting light before the exciting light reaches the measurement site of the thin film, (4) a probe light source for supplying probe light passing the measurement site or its vicinity, and (5) a detector for detecting an amount of deflection of the probe light having passed the measurement site or its vicinity. A method for measuring the light absorption characteristic of a thin film and an equipment for forming a monomolecular built-up film employing the above apparatus are also provided.
