Standard plane sample and optical characteristic measurement system

An optical characteristic measurement system for measuring an optical characteristic of an object, comprising:

• a standard plane sample comprising:
• a sample portion that is measured by an optical characteristic measuring device to supply measurement data;
• a recording medium that stores identification data for identifying a kind of the sample portion as well as reference data corresponding to an optical characteristic of the sample portion;
• and
• a communication portion that performs data transmission with the optical characteristic measuring device;
• and
• the optical characteristic measuring device comprising:
• a measuring portion that measures the object;
• a reading and writing portion that performs data transmission with the standard plane sample through the communication portion of the standard plane sample, and receives data stored in the recording medium of the standard plane sample from the communication portion of the standard plane sample;
• a sample data storage portion that stores the data received by the reading and writing portion;
• a comparator that compares, when it is determined that the standard plane sample is a standard plane sample for calibration based on the identification data, measurement data obtained upon measuring the sample portion of the standard plane sample by the measuring portion with the reference data received from the standard plane sample;
• a correction coefficient calculator that generates correction coefficient data based on a difference between the measurement data of the sample portion and the reference data;
• and
• a measurement corrector that generates corrected measurement data by applying the correction coefficient data on the measurement data obtained upon measurement of the object by the measuring portion.
