Abstract
The invention discloses a measurement instrument for removing influence of a size factor on color accuracy of a diamond. The measurement instrument comprises an integration ball with detecting equipment. A sample positioning device is mounted on an integration ball main body; and a sample positioning groove for bearing the diamond is arranged in the sample positioning device. According to the measurement instrument provided by the invention, the diamond color measurement is carried out by using an improved integration ball of an optical instrument, so that the problem of influencing the measurement accuracy by color difference, caused by different diamond sizes and different generated light ranges in the diamond color measurement, can be solved.
Description
Technical field
The present invention relates to a kind of surveying instrument, is a kind of diamond proterties surveying instrument, particularly a kind ofly eliminates the surveying instrument that size factor affects color accuracy of diamond.
Background technology
Appreciation has 4C standard, wherein color (color) is generally to light yellow classification by colourless, standard of perfection is general international standard, main with the standard of CIBJO (International Jewelry jewellery federation) and GIA (American Gem institute) for reference frame, than the standard of colored stone from colourless D level to the Z level of yellow.
The coloring mechanism of diamond is a quite complicated problem, is the focus that many research institutions pay close attention to for many years always.Under desirable state, diamond, owing to being complete regular system crystal, does not have selective absorbing in visible-range, therefore shows as colourless.But the colourless pure diamond of natural generation is very rare, and extreme portions diamond, because its very long growth course, is subject to the impact of extraneous growing environment, and makes its lattice sustain damage, and causes and occurs deep mixed color.
As can be seen from the universal knowledege of above-mentioned diamond color, diamond product affects the spectral power distribution that its color factors not only depends on lighting source, depends on the selective absorbing of diamond to visible spectrum itself simultaneously.For the diamond of same color, due to the difference in size of volume, the light path that light is propagated in diamond is different, and selective absorbing is different, can cause the difference measuring color like this.
Integrating sphere is a kind of optical instrument, for the high efficiency device of one that sample is collected the scattering of light or transmitting, can express the optical property of sample accurately.Be a kind of general integrating sphere as what represent in Fig. 1, figure, light source is by catoptron or directly enter the integrating sphere inside with detector and to beat on the carrier of bearing test sample thus measurement sample being carried out to optical property.In the present invention, the proposition of inventor's innovation adopts integrating sphere to be applied to the measurement of diamond color, thus improves the accuracy of diamond color measurement.But, as Fig. 2 and Fig. 3, what represent is the schematic diagram that the diamond sample of different volumes adopts common integrating sphere to measure, as can be seen from the figure light path D1+D2+D3 > d1+d2+d3, under this measuring condition, light is through the larger diamond of volume, the optical length produced, selective absorbing is just large, and the diamond causing color identical only produces color distortion because of volume difference, causes larger measuring error.So, must improve existing integrating sphere, produce a kind of instrument being specially adapted for diamond color measurement, thus the Measurement accuracy of diamond color can be reached.For the technical scheme that the present invention proposes, have no existing patent or document is reported.
Summary of the invention
The invention provides and a kind ofly eliminate the surveying instrument that size factor affects color accuracy of diamond, integrating sphere is introduced diamond color measurement, solves when diamond color measurement, because diamond size is different, the light path produced is different, thus produces the problem that color distortion affects accuracy of measurement.
The present invention is realized by following technical scheme:
Eliminate the surveying instrument that size factor affects color accuracy of diamond, comprise the integrating sphere with detecting devices, described integrating sphere body installs a sample positioning device, is the Sample location groove of carrying diamond in described sample positioning device.
Described Sample location groove cell body is cone.According to the cutting standard of diamond, the booth angle of diamond has uniform rules, and Sample location groove of the present invention meets the angle general standard at diamond booth angle.
The cone angle of described Sample location groove cell body is 98 °.According to diamond cutting standard, the booth angle of diamond sample is 98 °, makes different volumes diamond in integrating sphere have identical outcrop area like this, establishes the uniqueness condition of measurement.
Beneficial effect of the present invention is:
What 1, the present invention innovated have employed the instrument of optical instrument integrating sphere as diamond color measurement, is the application that integrating sphere is new, makes diamond color measurement more accurate.
2, the color measuring difference produced because diamond sample volume is different is solved.

Fig. 4 is the structure diagram of surveying instrument of the present invention
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
As Fig. 4, be the structure diagram of surveying instrument of the present invention, be a kind ofly eliminate the surveying instrument that size factor affects color accuracy of diamond, comprise the integrating sphere 1 with detecting devices 2, integrating sphere 1 body installs a sample positioning device 3, is the Sample location groove 4 of carrying diamond in sample positioning device.
Light source injects integrating sphere 1 of the present invention, cover sample positioning device 3 completely, make whole sample positioning device 3 all within the scope of light source, different for volume two test sample diamond A1 and A2 are placed on the Sample location groove arranged in sample positioning device 3 respectively, Sample location groove groove 4 body is cone, usual angle is 98 °, identical with common diamond booth angle.As Fig. 4, the measurement area of A1 with A2 is identical in detail in this figure, and what detecting devices 2 was measured comes to the same thing, then color measuring result is accurate.
The present invention innovates and adopts optical instrument integrating sphere as diamond color measurement instrument, improves, eliminate the error problem due to different volumes diamond color measurement to existing integrating sphere.
