By including an illumination system and a detection system, an information collecting function of monitoring an environment, such as temperature and atmospheric pressure, and an apparatus state managing function having a feedback function of comparing the monitoring result and a design value, a theoretical calculation value or an ideal value derived from simulation results and calibrating an apparatus so that the monitoring result is brought close to the ideal value, a unit for keeping the apparatus state and apparatus sensitivity constant is provided. A control unit 800 is configured to include a recording unit 801, a comparing unit 802, a sensitivity predicting unit 803, and a feedback control unit 804. In the comparing unit 802, the monitoring result transmitted from the recording unit 801 and an ideal value stored in a database 805 are compared with each other. When a difference between the ideal value and the monitoring result exceeds a predetermined threshold, the feedback control unit 804 corrects the illumination system and the detection system.
