According to the folding-type polarizer diachroscope, the distance between the eye and the observation window is increased, a user can adjusts a proper observation distance, the range of the observation vision field is expanded, the resolution degree of polychroism is improved, and for the user with poor eyesight, glasses can be wore for use.
Description
Technical field
The utility model relates to a kind of dichroscope, relates in particular to a kind of collapsible polaroid dichroscope, for observing the pleochroism of coloured monocrystalline jewel, belongs to jewel qualification equipment field.
Background technology
For the anisotropic coloured monocrystalline jewel of photosensitiveness, will resolve into the orthogonal polarized light of two bundle direction of vibration along the natural light of non-optical axis direction incident.This two bundle polarized light by jewel not equally selectivity absorb, form color there are differences two bundle polarized lights.Dichroscope can be separated this two bundles polarized light, is used for observing the pleochroism of colored gemstone.
The dichroscope using is in the market icelandspar dichroscope, and it is made up of parts such as glass prism, icelandspar faceted pebble body, lens, object lens and eyepieces, as shown in Figure 4.
Mainly, when use, eyes need be pressed close to eyepiece to the shortcoming of prior art, and the user who wears glasses can operate inconvenience; The observation ken is little, and resolution is low, and focal length fixes, and caliginous user may observe fuzzy image.
Summary of the invention
The purpose of this utility model is:
In order to overcome the problem of prior art existence, increase the distance of eyes and watch window, user can adjust suitable viewing distance, has expanded the scope of observing the ken simultaneously, has improved pleochromatic resolution degree.Caliginous user can use by wearing spectacles.
The purpose of this utility model can realize by following technical scheme:
A kind of collapsible polaroid dichroscope; comprise lens protection shell; semicircle polaroid; lens frame; described lens protection shell is the hollow shell-like structure that at least has upper and lower surface shell sheet and have a side opening at least; in lens frame, be fixed with two orthogonal semicircle polaroids in polarization direction, one end of lens frame one end and lens protection shell is hinged to be made lens frame pass through to rotate can be covered by lens protection shell.
In described lens frame, be provided with dismountable eyeglass fixed frame.
Described eyeglass fixed frame is connected with lens frame main body by buckle or spiral form.
The beneficial effects of the utility model are:
Increased the distance of eyes and watch window, user can adjust suitable viewing distance, has expanded the scope of observing the ken simultaneously, has improved pleochromatic resolution degree.Caliginous user can use by wearing spectacles.

Fig. 3 is polaroid principle schematic.
Fig. 4 is the dichroscope structural representation of prior art.
Wherein:
1, lens protection shell; 2, semicircle polaroid; 3, lens frame; 4, eyeglass fixed frame; 5, shell sheet; 6, opening; 7, rotating shaft.
8, glass prism; 9, icelandspar faceted pebble body; 10, lens; 11, object lens; 12; Eyepiece.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The utility model provides a kind of collapsible polaroid dichroscope; as shown in Figure 1, comprise lens protection shell 1, semicircle polaroid 2; lens frame 3, described lens protection shell 1 is the hollow shell-like structure that at least has upper and lower surface shell sheet 5 and have a side opening 6 at least.As shown in Figure 2, be fixed with two orthogonal semicircle polaroids 2 in polarization direction in lens frame 3, the hinged lens frame 3 that makes in one end of lens frame 3 one end and lens protection shell 1 can be covered by lens protection shell 1 by rotating.The material of described semicircle polaroid 2 can be glass, can be also organic material, preferably uses organic material, so that cut out.Lens protection shell 1 preferably adopts metal material, to protect better and fixing polaroid.
In described lens frame 3, be provided with dismountable eyeglass fixed frame 4, eyeglass fixed frame 4 is connected with lens frame 3 main bodys by buckle or spiral form, so that installation and removal polaroid.
Principle of work of the present utility model is:
Polaroid is the dichroiscopic core component of collapsible polaroid.The effect of polaroid is that incident light is resolved into two mutually orthogonal polarized light components, and horizontal P component and vertical S component (taking from German Senkrecht and Parallel), only allow one-component pass through, and another component is absorbed or is scattered.From the polarized light of colored gemstone, by only having the polarized light consistent with polaroid polarization direction to pass after polaroid, as shown in Figure 3.
In the time that the polarization direction of two polaroids in left and right is consistent with the direction of vibration of the two bundle polarized lights from colored gemstone respectively, can observe the pleochroism of this colored gemstone.
The dichroiscopic making step of collapsible polaroid of the present utility model is:
1, can demarcate by WSZ polarized light pilot system the polarization direction of polaroid, or demarcate the polarisation range estimation demarcation of polarization direction by a slice.
2, two semicircles in polaroid being cut into shown in Fig. 2, the orientation of attention polarization direction, after amalgamation, the polarization direction of two semicircle polaroids 2 is mutually vertical.
3, by fixing the sheet of face-piece up and down of lens protection shell 15, available fixed screw is fixed.
4, one end of lens frame 3 is snapped in the middle of the upper lower casing sheet 5 of lens protection shell 1, by fixing to lens protection shell 1 and lens frame 3 use rotating shafts 7.
5, two semicircle polaroids 2 are combined into a circle, are placed on lens frame 3 with removable lens fixed frame 4.
As shown in Figure 4, the dichroscope using is in the market icelandspar dichroscope, and it is made up of parts such as glass prism 8, icelandspar faceted pebble body 9, lens 10, object lens 11 and eyepieces 12.When use, eyes need be pressed close to eyepiece, and the user who wears glasses can operate inconvenience; The observation ken is little, and resolution is low, and focal length fixes, and caliginous user may observe fuzzy image.
Collapsible polaroid dichroscope of the present utility model has increased the distance of eyes and watch window, and user can adjust suitable viewing distance, has expanded the scope of observing the ken simultaneously, has improved pleochromatic resolution degree.Caliginous user can use by wearing spectacles.
Below the dichroiscopic result of use comparison of icelandspar of collapsible polaroid dichroscope of the present utility model and prior art:
| ? | Icelandspar dichroscope | Collapsible polaroid dichroscope of the present utility model |
| Eyes are apart from the distance of watch window | 2～3 centimetres | 2～50 centimetres |
| Observe the size of the ken | Very little | Diameter is the circle of 2 centimetres |
| Whether there is the device of protection eyeglass | Nothing | Have |
| Whether facilitate wearing spectacles | No | Be |
Although here describes and illustrate the utility model by certain or some particular arrangement, but its object do not lie in the described details of restriction, because may have various amendments and structure modify in patent claimed range, does not depart from invention spirit.
The utility model relates to partly all prior aries that maybe can adopt same as the prior art to be realized.
