名词 n.
  1. An instrument used to test for color blindness by measuring quantitative and qualitative anomalies in color perception.
    — The anomaloscope contains a red-green scale from which may be read a number that is proportional to the amount of red in the mixture field, and a Y scale from which is read a number proportional to the luminance of the test color. In testing an observer, the examiner notes the scale values, which then are available for further transformation as noted for the Nagel anomaloscope.
