Calibration of optical instruments is important for accurate measurement of the absolute emission intensity of aurora and airglow. The National Institute of Polar Research (NIPR), Japan, has been operating a facility for the optical calibration which consists of three independent calibration systems to share with collaborating researchers. This paper introduces an outline of the facility and specifications of each system, calibration procedures, and examples of calibration results. With this facility, we can obtain the calibration data for the absolute sensitivity of optical instruments with an accuracy of about 2% within a wavelength range between 420 and 1050 nm. In addition, it is possible to calibrate transmission of optical filters and also relative sensitivity of optical instruments as a function of wavelengths. Current facility, upgraded in 2012, has been used by many researchers to calibrate their various optical instruments.

NIPR光学校准系统,用于极光和气辉观测

光学仪器的校准对于准确测量极光和气辉的绝对发射强度非常重要。日本国立极地研究所(NIPR)一直在运营一种光学校准设备,该设备由三个独立的校准系统组成,与合作研究人员共享。本文简要介绍了每个系统的功能和规格,校准程序以及校准结果示例。使用此工具,我们可以在420至1050 nm的波长范围内以约2%的精度获得光学仪器绝对灵敏度的校准数据。另外,可以校准滤光器的透射率以及光学仪器相对于波长的相对灵敏度。现有设施
