Abstract
The utility model provides a kind of eyeglass that can provide the stable number of degrees in various medium, refers in particular to a kind of biplane concavees lens.Be mainly plane concavees lens, wherein, the concave surface of the monoplane concavees lens of two formed objects fits and forms the pure flat biplane concavees lens of inner hollow, outside surface.Under normal circumstances, concavees lens hollow space fills air; Use in the environment that the temperature difference is larger, hollow space is filled refractive index and is less than the transparency material of lens materials or is evacuated, and can avoid the serviceable life of influence of temperature change eyeglass and the eyes of injury myopia.The utility model structure is simple, this eyeglass is made no matter to be placed in vacuum, air by this array mode or being fully immersed in liquid all can keep the stable number of degrees and focal length, this eyeglass is not only suitable as swimming glasses, is also applicable under water, the equipment of alternately operating waterborne.
Description
Technical field
The utility model relates to optics technical field, refers in particular to a kind of biplane concavees lens.
Background technology
At present, suffer from bathomorphic patient and not only trend towards rejuvenation, and quantity being in rising trend every year, for suffering from bathomorphic patient, in daily life, only need wear secondary spectacles; But, when the myopia Shi Zehui that goes swimming or swim underwater runs into many troubles, such as do not see during swimming surrounding environment, easily and companion scatter, debark after the article such as shoes and hats, spectacles be placed on sandy beach often can not find etc.
For the problems referred to above, sell a kind of Myopic goggles on the market, it is mainly by plane and the extraneous contact of plate plane concavees lens, concave surface is hidden in swimming glasses inside and does not contact with water, to reduce the difference with the number of degrees in air in water, but, larger on the impact of the number of degrees when this Myopic goggles is positioned at different medium or temperature, when number of degrees change is easy frequently, patient's eye is tired, is harmful to and deepens the number of degrees further to eye.
Summary of the invention
The purpose of this utility model is for the existing state of the art, provides a kind of biplane concavees lens, keeps the comparatively stable number of degrees in water or in air, the eyes of protection myopia.
For achieving the above object, the utility model adopts following technical scheme:
The utility model is a kind of biplane concavees lens, has plane concavees lens, and the concave surface of the monoplane concavees lens of two formed objects fits and forms the pure flat biplane concavees lens of inner hollow, outside surface.
In such scheme, the hollow space of biplane concavees lens is air.
As preferred technical scheme, the hollow space of biplane concavees lens is filled refractive index and is less than the transparency material of lens materials or is evacuated, can use in the environment that the temperature difference is larger, avoid the serviceable life of influence of temperature change eyeglass and the eyes of injury myopia.
In such scheme, the transparency material that refractive index is less than lens materials can be helium, hydrogen etc.
The beneficial effects of the utility model are:
1. no matter biplane concavees lens of the present utility model are placed in vacuum, air or invade bubble completely in a liquid, and its number of degrees, focal length can remain unchanged;
2. can be used for myopia diving, swimming goggle;
3. can this eyeglass be placed in outside the viewport of the subsea equipments such as submarine, expand range of observation;
4. utilize the principle of similitude to make magnifier under water, for observing seabed atom, to make " farsightedness diving swimming goggle " or " astigmatic eyes diving swimming goggle ";
5. can be made into the camera lens of various amphibious picture pick-up device.
accompanying drawing illustrates:
Accompanying drawing 1 is cross-sectional view of the present utility model;
Accompanying drawing 2 is the cross-sectional view that biconcave lens is combined with flat mirror.
embodiment:
Can have the object of the utility model, feature and function to make juror and further understand, hereby lift preferred embodiment and coordinate graphic being described in detail as follows:
Refer to shown in Fig. 1, it is the structural representation of the preferred embodiment of the utility model, the utility model is the utility model is a kind of biplane concavees lens, the concave surface with the monoplane concavees lens 1 of plane concavees lens 1, two formed objects fits and forms the pure flat biplane concavees lens of inner hollow, outside surface.
In such scheme, hollow 2 part of biplane concavees lens is air.
As preferred technical scheme, the hollow 2 of biplane concavees lens is partially filled refractive index and is less than the transparency material (as helium, hydrogen etc.) of lens materials or is evacuated, can use in the environment that the temperature difference is larger, avoid the serviceable life of influence of temperature change eyeglass and the eyes of injury myopia.
Shown in Fig. 2, as another kind of embodiment: biconcave lens 3 both sides concave surface all can be sticked the flat mirror of one deck, the transparency material that refractive index is less than concavees lens material can be filled in the space that the concave surface of biconcave lens 3 and flat mirror 4 are formed.
Certainly, above diagram is only the utility model better embodiment, not limits usable range of the present utility model with this, therefore, every make in the utility model principle equivalence change all should be included in protection domain of the present utility model.
Claims (4)
1. biplane concavees lens, have monoplane concavees lens, it is characterized in that: the concave surface of the monoplane concavees lens of two formed objects fits and forms the pure flat biplane concavees lens of inner hollow, outside surface.
2. a kind of biplane concavees lens according to claim 1, is characterized in that: described hollow space is air.
