摘要
To ensure measurement accuracy and reliable, and adapt to the development of the infrared transmittance calibration needs in China, this paper introduces the mid-infrared regular transmittance bilateral comparison organized by the China National Institute of Metrology. This comparison mainly focused on the wavelength band of 4000 cm(-1)-400cm(-1)(2.5 mu m -20 mu m). Technical protocol, facilities, measurement methods and conditions, and uncertainties from the participating laboratories have also been introduced.
