Introduction

This procedure is based on the JJG 981-2003 reference JJF1002-2010 "national verification procedures compiled Write Rules "re-revised. Compared with JJG 981-2003, except in accordance with section JJF1002-2010 made constitution And modify the formatting on the outside, the main technical changes are as follows. --- Increasing the reference document (see Chapter 2); --- Increasing the term (see Chapter 3); --- Increase the measuring instruments in control of "the refractive index of the glass material standard block" requirements (see 7.1.1.4); --- Modify the measurement sequence verification method (see 7.3.3); --- Increase the verification process reads the V prism refractometer real time correction value d requirements (see 7.3.3.5); --- Modify the original record test recommended format (see Appendix B); --- Adjustment Appendix order. The previous versions of this Recommendation published case. --- JJG 981-2003. Abbe refractometer standard block verification procedures

3 Terms

The following terms and definitions apply to this procedure. 3.1 refractive index n (λ) refractiveindex Electromagnetic wave velocity in a vacuum with a monochromatic radiation of different wavelengths in the medium than the corresponding speed. Note. A practical application, the air velocity in a vacuum instead of speed. Helium is usually a refractive index of the yellow line d 2 of the optical material (wavelength λ of 587.56) or refractive index nd mercury green line e (wavelength λ As 546.07nm) refractive index to represent. 3.2 Dispersion dispersion Monochromatic radiation of different wavelengths in the refractive index of the medium changes due to the different wavelengths of the phenomenon. 3.3 Abbe number vd Abbenumber Also known as chromatic dispersion coefficient is a mathematical expression characterizing optical material dispersion phenomena, usually with vd = nd-1nF-nC Or ve = ne-1nF'-nC ' To represent. Note. 1 nd helium yellow line d (wavelength λ is 587.56nm) refractive index; nF hydrogen blue line F (wavelength λ is 486.13nm) of nC hydrogen red line C (wavelength λ is 656.27nm) refractive index; refractive index. ne mercury green line e (λ is the wavelength 546.07nm) refractive index; nF 'cadmium blue line F' (λ is the wavelength 479.99nm) refractive index; nC 'mercury red line C' (Wavelength λ of 643.85nm) of the refractive index. 2 (nF-nC) called average dispersion, also called the central dispersion. 3.4 Abbe refractometer Abberefractometer Using the principle of total reflection critical angle, measured transparent, translucent liquid or solid refractive index (nD) and average Dispersion (nF-nC) of the instrument. Equipped with a calibration sample block is called work sample block. Note. nD sodium yellow line D (wavelength λ is 598.30nm) index of refraction. ...
