Description
Technical field
The utility model relates to gem testing instrument device fields, and in particular to gem refractometer fixes swivel mount with jewel.
Background technique
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 enters the thin substance of the light less than the light of critical angle, can not see these light 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.One scale is installed under eyepiece, is carved with refractive index value corresponding with this critical angle, the instruction of light and shade domain border
Numerical value, that is, measured matter refractive index.To make tested jewel interface reach closely sealed contact with prism table top, the two asks that it is still necessary to add
One drips the immersion oil (common high refractive index immersion oil n=1 80) that its refractive index is higher than jewel lower than prism material, therefore, surveys treasured
It attends school if the refractive index of stone is 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 measurement dispersion values.
It the use of the method that gem refractometer detects jewel include long sight method and facet method, two methods are required to
Jewel is ceaselessly rotated when detection.Entire jewel needs to rotate 360 degree when facet method detects, detection process in it is precious
Every 15 degree of the rotation of stone, with regard to carrying out single reading and recording, but using usually rotational angle is inaccurate when both hands rotation jewel
Really；To the case where gemstone angle is less than 360 degree or more than 360 degree occur, so that the result inaccuracy of detection；And it is double
Hand rotates very inconvenient when jewel.When long sight method is detected, need to rotate always jewel until in eyepiece
Until seeing circular droplet, but since the rotational angle of hand is inaccurate, so that there are certain errors for testing result.
