Summary of the invention
Purpose of the present invention just provides a kind of method for quick of emerald, with the simplest mode emerald or antiques are carried out fast detecting, detects imitative product, avoids having dust thrown into the eyes.
The present invention is achieved in that a kind of method for quick of emerald, detects and carries out according to the following steps:
A, the surface of inspected object is cleaned;
B, tester's handheld portable LED ultraviolet source shine the surface of inspected object, namely have the hot spot of irradiation to produce on the surface of inspected object;
C, tester hand a ultraviolet filtering mirror and by the irradiation hot spot on this ultraviolet filtering mirror observation inspected object, the power of non-blooming generation and fluorescence generation are arranged on the observation irradiation hot spot;
D, mobile portable LED ultraviolet source or movement, upset inspected object make portable LED ultraviolet source irradiation at the different surfaces of inspected object or the different parts on same surface, carry out multipoint observation.
The wavelength of the ultraviolet light that described portable LED ultraviolet source sends is 360-400nm.
The wavelength of light of described ultraviolet filtering mirror institute filtering is 10-400nm.
Testing process is carried out at place indoor or backlight, avoids carrying out under direct irradiation of sunlight.Described inspected object is placed on the dark substrate.
Ultraviolet wavelength is 10-400nm, and spectrum is between visible light and X ray.Although its wavelength ratio visible light is short, can not arrive for human eye is observed, but the light reaction that a lot of materials present under the irradiation of ultraviolet light is different, modern chemical industry synthetic material and macromolecular material that particularly various pigment, wax and organic gel etc. are modelled after an antique, emulation is commonly used, it all can send significantly or stronger Ultraluminescence under the irradiation of ultraviolet light, and this is main and obvious characteristics that are different from natural jadeite and genuine piece antique, calligraphy and painting.Therefore, detection method of the present invention just is mapped on the inspected object with the ultraviolet lighting that little, lightweight, luminous good, an easy to carry portable LED ultraviolet source of volume is sent out, to observe the effect of its fluorescence reaction.But, because the sensory effects of the Ultraluminescence that the ultraviolet reflectance light that ultraviolet source irradiation produces to inspected object surface and inspected object itself produce is more approaching, human eye is not easily distinguishable, so, the present invention uses a ultraviolet filtering mirror to carry out preferably filtering to ultraviolet reflectance light, is that to go out what produce on inspected object be ultraviolet reflectance light or Ultraluminescence to observable on earth thus.If there is Ultraluminescence to produce, can affirm that inspected object processed through manual method, just belong to the modern times to imitate product.
Detection method of the present invention is not subjected to the restriction of instrument and equipment, and everybody can grasp and use, and the scene can be detected, operate very simple, and identification result quicklook; Owing to not having the restriction of machine box cabinet etc., so big or small article all can arbitrarily detect.Detection method of the present invention is suitable for the various articles such as emerald, gambling stone, antiques, calligraphy and painting, strange stone and jewel are detected, and can satisfy multiple ornament or the consumer of collection and trader's the use needs such as emerald, jewel, antiques, calligraphy and painting.
Description of drawings
Fig. 1 is detection principle schematic of the present invention.
Embodiment
In conjunction with shown in Figure 1, detection method of the present invention is to carry out according to the following steps:
A, the surface of inspected object is cleaned;
B, at place indoor or backlight, the tester hands the portable LED ultraviolet source 1 that wavelength is 360-400nm, and the surface that is placed on the inspected object 3 on the dark substrate is shone, and produces the irradiation hot spot on the surface of inspected object 3;
C, the hand-held ultraviolet filtering mirror 2 that the filtering wavelength of light is 10-400nm of tester by the irradiation hot spot on these ultraviolet filtering mirror 2 observation inspected object 3, are looked at the power that has non-blooming generation and fluorescence to produce at the irradiation hot spot;
D, mobile portable LED ultraviolet source, perhaps mobile, upset inspected object makes portable LED ultraviolet source irradiation at the different surfaces of inspected object or the different parts on same surface, carries out multipoint observation.
For emerald, if there is not fluorescence to produce when detecting, then can assert it is emerald A goods.If used organic substance to carry out artificial treatment at emerald, shining so just has behind the emerald fluorescence to produce, and the luminosity of fluorescence is stronger, and this emerald just can assert it is emerald B goods or B+C goods.If used coloring agent etc. at emerald, shining so also has behind the emerald fluorescence to produce, and the color on the emerald can shoal or have slight variable color, and this emerald just can assert it is emerald C goods.
For gambling stone, to use the high molecular polymerization materials such as a lot of bonding agents during owing to fraud, therefore under the LED ultraviolet source irradiation, use the ultraviolet filtering sem observation, can form fluorescence reaction fragmentarily on the surface of gambling stone, natural gambling stone does not then have this situation to occur.
For antiques, calligraphy and painting etc., to use a lot of high molecular polymers such as glue, resin or plastics during owing to antique-imitation, therefore article surface can produce fluorescence when detecting.Other such as old china, ancient painting and ancient furniture etc. as finding that article surface has part or whole fluorescence reaction, all can assert it is imitative product when detecting.
For synthetic gems, owing to being to add beautiful powder with the artificial stone resin to make a lot, have fluorescence reaction when therefore detecting.
For strange stone, if the strange stone of the fraud of bonding amalgamation is then used the ultraviolet filtering sem observation under the LED ultraviolet source irradiation, can find apparent in view fluorescence in the junction, this is the fluorescence reaction of cementing agent; If by dyeing or the artificial synthetic strange stone of fraud, then its color can be faded under the irradiation of LED ultraviolet source.
For jewel, because its kind is more, therefore, use detection method of the present invention, the discriminating personnel that need to have professional level just can make more accurately and detecting.
