Description
Technical field
The present invention relates to gem testing instrument device fields, and in particular to gem refractometer fixes swivel mount with jewel.
Background technology
Gem refractometer (gem refractometer) is for measuring the instrument that gem and jade chisels part refractive index.It is with one
Homogenieity material (such as lead glass or synthesis of cubic zirconium oxide) hemisphere of high refractive index makees prism；Light is tested by prism directive to dredge
The light of substance, the light less than critical angle dredge substance into the light, these light are can not see on eyepiece, show as a dark domain；Greatly
It is all-trans in the light of critical angle and is emitted back towards prism, a bright domain is shown on eyepiece；It is critical that the line of demarcation in light and shade domain is equivalent to this
The position at angle.Installation is there are one scale under eyepiece, be carved with the corresponding refractive index value of this critical angle, the instruction of light and shade domain border
The refractive index of numerical value, that is, measured matter.For tested jewel interface is made to reach closely sealed contact with prism table top, the two asks that it is still necessary to add
One drips its refractive index less than prism material and higher than the immersion oil (common high refractive index immersion oil n=1 80) of jewel, therefore, surveys treasured
If the refractive index of stone is attended school higher than immersion oil less than correct result.Refractometer can not only measure refractive index, the birefringence of gem and jade,
It is positive and negative to may further be used to sentence gyroscopic inertia, photosensitiveness, uses monochromatic source or colour filter, it may also be used for measures dispersion values.
Long sight method is included to the method that jewel is detected using gem refractometer and facet method, two methods are required to
Jewel is ceaselessly rotated when detection.Facet method detect when entire jewel need rotation 360 degree, detection process in treasured
Stone often rotates 15 degree, with regard to carrying out single reading and recording, but using usually rotational angle is not allowed when both hands rotation jewel
Really；So as to situation of the gemstone angle less than 360 degree or more than 360 degree occur so that the result of detection is inaccurate；It is and double
Hand rotates very inconvenient when jewel.When long sight method is detected, need to rotate jewel always until in eyepiece
Until seeing circular droplet, but since the rotational angle of hand is inaccurate, so as to testing result, there are certain errors.
