Description

Technical Field

[0001] The utility model relates to the technical field of jewelry detection, and specifically, to a gemstone polarization light shielding observation device. Background Art

[0002] A polarizing microscope is mainly used to distinguish homogeneous gemstones and inhomogeneous gemstones and crystalline (cryptocrystalline or microcrystalline) aggregates, and to identify the anomalous birefringence phenomenon of gemstones. It can be used to judge the optic axis of gemstones and check the pleochroism of gemstones.

[0003] Under specific circumstances, with the help of a conoscopic microscope, the interference pattern of a gemstone can be observed to determine the optic axis of the gemstone. When natural light passes through the lower polarizer, polarized light is generated. If the upper polarizer and the lower polarizer are parallel, all the polarized light from the lower polarizer passes through, and the field of view is the brightest; if the upper polarizer and the lower polarizer are perpendicular, all the polarized light from the lower polarizer is blocked, and the field of view is the darkest at this time, that is, extinction occurs.

[0004] However, during the use of a common gemstone polarizing microscope, when irradiating the gemstone, the light is relatively scattered, resulting in incomplete observation during the polarization detection of the gemstone. In view of this, a gemstone polarization light shielding observation device is developed. Content of the Utility Model

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1 to 3 shown, this embodiment proposes a gemstone polarization light shielding and observation device, including

[0024] The placement table 1 is provided with an observation mirror 2 thereon;

[0025] The lighting and observation assembly 3 is arranged on the placement table 1;

[0026] The flipping and shielding assembly 4 is arranged on the upper end face of the placement table 1;

[0027] The lighting and observation assembly 3 includes an irradiation cavity 3-1 which is opened in the placement table 1. A mapping lens 3-2 is arranged on the placement table 1. A limiting sleeve 3-3 is sleeved on the outer surface of the mapping lens 3-2. The limiting sleeve 3-3 is arranged on the upper end face of the placement table 1. The limiting sleeve 3-3 is embedded in the placement table 1. The limiting sleeve 3-3 is communicated with the irradiation cavity 3-1. An installation frame 3-4 is arranged on the upper end face of the placement table 1. An observation piece 3-5 is arranged on the installation frame 3-4.

[0028] In this embodiment, a gemstone is placed on the mapping lens 3-2, and the gemstone is observed through the observation mirror 2 on the installation frame 3-4.

[0029] Specifically, the observation mirror 2 has the same shape as the mapping lens 3-2, and the positions of the observation mirror 2 and the mapping lens 3-2 correspond to each other. An irradiation lamp 3-6 is arranged in the irradiation cavity 3-1.

[0030] In this embodiment, the irradiation lamp 3-6 irradiates light. After the light is emitted from the irradiation cavity 3-1, the light irradiates out from the mapping lens 3-2, and the observation is carried out after the light passes through the mapping lens 3-2 on the limiting sleeve 3-3.

[0031] Further, the flipping and shielding assembly 4 includes a mounting block 4-1 which is arranged on the side surface of the limiting sleeve 3-3. A light-shielding cover 4-2 is pin-connected to the mounting block 4-1, and the light-shielding cover 4-2 is buckled on the limiting sleeve 3-3.

[0032] In this embodiment, the light-shielding cover 4-2 can be flipped through the mounting block 4-1. During use, the light-shielding cover 4-2 is buckled on the limiting sleeve 3-3 for light shielding, so that the observation effect is better and not affected by external light.

[0033] Further, a placement sleeve 5 is arranged on the upper end face of the placement table 1. The lower end of the observation mirror 2 is inserted into the placement sleeve 5. A limiting groove 6 is arranged on the upper end face of the limiting sleeve 3-3. The lower end face of the light-shielding cover 4-2 is embedded in the limiting groove 6.

[0034] In this embodiment, the placement sleeve 5 is used to prevent the observation mirror 2, and the limiting groove 6 is used for the limitation of the light-shielding cover 4-2, so that the light of the light-shielding cover 4-2 does not leak out.

[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
