1 Scope

This standard specifies the infrared optical glass infrared refractive index test principle, test equipment, samples, environmental requirements, test ho steps, data Management, measurement uncertainty and test reports. This standard applies to deflection angle method infrared optical glass infrared refractive index test, infrared refractive index of other infrared materials Test can refer to use.

2 Terms and definitions

The following terms and definitions apply to this document. 2.1 Infrared refraction index The refractive index of optical materials in the infrared band, with nλ said. 2.2 Infrared dispersion coefficient infrareddispersioncoefficient Changes in the refractive index of different infrared wavelength range known as infrared dispersion, with infrared dispersion coefficient. Three atmospheric window 1μm ~ The infrared dispersion coefficients of 3 μm, 3 μm to 5 μm, and 8 μm to 12.5 μm are expressed by υ2, υ4, and ν10.6, and are expressed as follows. υ2 = (n2-1)/(n1-n3) υ4 = (n4-1)/(n3-n5) υ10.6 = (n10.6-1)/(n8-n12.5)

3 test principle

Wavelength λ infrared parallel beam incident on the apex angle α of the sample AB surface, the light deflection occurs, the injection from the AC plane, through After measuring the incident angle i and the refraction angle φ, the refractive index nλ of the material at the wavelength λ is calculated. Deflection angle infrared refractive index test principle shown in Figure 1. ......
