Abstract
The utility model provides a magnifier with double lenses, which comprises a magnifier frame, convex lenses, a purple lamp, a white lamp and a battery; two lens placing areas are arranged in the magnifier frame; two convex lenses are arranged in the two lens placing areas respectively; and the purple lamp and the white lamp are used for lighting one convex lens. Due to the structure, two magnifiers for gem identification are organically combined together to facilitate the identification of various gems; meanwhile, various demands of people are also met.
Description
Technical field
The utility model relates to the jewel evaluation apparatus, a kind of two lens magnifier that jewel is identified that is used for of saying so exactly, and this magnifier can be used in differentiates diamond, the refraction situation of bullion under the different light rays effect, thinks that the evaluation of specialty provides foundation.
Background technology
Magnifier is the most basic outfit of jewel research, inclusions, birefringence ghost image and other details of using magnifier to can be used to observe jewel.The used magnifier of research jewel is different from common magnifier; The multiplying power of general magnifier is not enough, and image can cause crookedly at the picture frame edge, thereby can not be used for observing jewel.Jewel is less with the size of magnifier, and has used two convex lens, makes it after the precision design, higher enlargement ratio is arranged and do not have crooked image.Usually used jewel does not wait at 10x～22x with the multiplying power of magnifier, and jewel selects 10 times of persons best with the magnifier multiplying power, there is no need to be higher than this multiplying power; If very will observe more powerful details, that just have to use microscope.10 times of jewel magnifieres, size has only several centimeters sizes, is easy to carry, even allow the researcher not have under the situation of other exact instrument, also can do preliminary observation to jewel.
Above-mentioned magnifier, only be the refraction of natural light to be observed by jewel, the scope and the condition of observing are limited, tend to have influence on assessor's judged result, the applicant has proposed bi-colour light source magnifier on Dec 31st, 2008, the structure of this magnifier is provided with purple lamp and white lamps by the top and the bottom at convex lens, make magnifier can realize the irradiation of two kinds of light sources, be convenient to the radiation of jewel assessor by different light rays, jewel is carried out comprehensively, identify exactly, and this magnifier is just assembled convex lens and power supply by a picture frame, and is simple in structure, volume is little, is easy to carry.
Yet, sometimes, identify that the jewel person is the personnel that jewel had certain professional knowledge, it only needs common magnifier just can identify, just under the situation that is difficult to differentiate, just need to cooperate light to discern, judge, therefore be necessary to provide a kind of magnifier of evaluation jewel that can be general, to satisfy user's various demands.
The utility model content
Based on this, the utility model provides a kind of magnifier with two lens, and the method that this magnifier can provide two kinds of jewels to identify is convenient to the assessor and is used according to oneself needs.
Another purpose of the present utility model is to provide a kind of magnifier with two lens, and this magnifying glass is simple, volume is little, is easy to carry.
The utility model is achieved in that
A kind of magnifier with two lens, include picture frame, convex lens, purple lamp, white lamps and battery, it is characterized in that being provided with in the picture frame two lens settlements, differentiate two convex lens are set, described purple lamp and white lamps are used for convex lens are thrown light on.
Described purple lamp and white lamps are arranged at the upper and lower of convex lens respectively, so that these convex lens are thrown light on.
Described two convex lens are respectively convex lens one and convex lens two, and convex lens one top is provided with the purple lamp, and below or side, below are provided with white lamps.
Described purple lamp is the LED lamp, around the top periphery that is arranged on convex lens one.
Described picture frame, its lens settlement for convex lens two is provided with a dividing wall, and convex lens one and convex lens two are kept apart, and avoids the phase mutual interference of the two.
Above-mentioned dividing wall, for settling open column, convex lens two are arranged to be settled in the open column, and complete and convex lens one are kept apart.
Described picture frame, it is divided into loam cake and lower cover two parts, and two parts fasten mutually, form whole picture frame.Picture frame is divided into two parts up and down, is convenient to processing and fabricating.
Described magnifier, its picture frame is arranged with movable sleeve outward, and the vertical cross-section of movable sleeve is a U-shaped, and picture frame is embedded in the U-shaped, and movable sleeve has protective effect to picture frame.
Described movable sleeve, the position up and down of one side are provided with and fasten projection, and the correspondence position of picture frame then is provided with shrinkage pool, and the fastening projection is chimeric with shrinkage pool, picture frame is embedded in the movable sleeve, and can be rotated.
The utility model adopts said structure, will identify that the employed two kinds of magnifieres of jewel organically are incorporated into together, is convenient to various jewels are identified, has also satisfied people's multiple demand simultaneously.
And above-mentioned magnifier, simple in structure, be easy to realize that volume is little, is easy to carry.
Description of drawings
The structure explosive view that Fig. 1 implements for the utility model.
Embodiment
Below in conjunction with accompanying drawing, enforcement of the present utility model is described further.
Shown in Figure 1, the utility model mainly includes picture frame, battery 9, purple lamp 4, white lamps 7, gauge tap 2 and convex lens 1 and convex lens 26.
Wherein, picture frame is divided into loam cake 1 and lower cover 8, gauge tap 2 is exposed from loam cake 1, and loam cake 1 is provided with two lens settlements simultaneously: lens settlement 1 and lens settlement 2 13 are provided with convex lens 1 in the lens settlement 1, convex lens 1 are Φ 21mm, 10 times of three layers of eyeglasses, its upper edge is provided with purple lamp 4, and purple lamp 4 adopts the LED lamp, have a plurality of, evenly around be arranged on convex lens 1 around; Suppress by a clear plastic ring 3 top of purple lamp 4, avoids coming off of purple lamp 4; White lamps 7 is arranged at a side of convex lens one 12 belows, is fixed on the white lamp socket 18, and white lamps 7 is white white temperature lamps that diamond is identified usefulness, and white lamps 7 adopts warm white LED lamp, 5300～5500GIA standard color temperature.
