Abstract
The utility model relates to a liquid optic lens, which belongs to the technical field of optical technology. The utility model is composed of a lens barrel, lenses, optical liquid, etc. The utility model is characterized in that both ends of the lens barrel are respectively provided with a thin optical glass lens whose central thickness is regulated by inner liner, a cavity is formed, optical liquid is poured in the cavity, and the liquid optic lens is formed. Because the central thickness is adjustable, the structure of the utility model can be adjusted. Because the optical liquid can be changed, the utility model has variability, so that the influences and difficulties caused by physical factors and chemical factors during the process of manufacturing large-scale optical glass and large-scale optical lenses can be avoided. The utility model has the advantages of simple structure, easy fabrication, and low cost.
Description
The utility model is a kind of optical lens, and particularly a kind of optics of liquids lens belong to optical technical field.
Common optical lens is to be formed by the optical glass attrition process, and the volume of optical glass is restricting the size of optical lens.Making large-scale optical lens needs large-scale optical glass, owing to be subjected to the influence of physics and chemical factor, large-scale optical glass production and large-scale optical lens manufacturing all exist certain difficulty.
The purpose of this utility model just provides a kind of optical glass of using, the optical lens that construction material and optics liquid are made.
The utility model optics of liquids lens are made up of lens barrel (1), eyeglass (2) and (3), neck bush (4), packing ring (5), volution (6), liquid injection hole (7), optics liquid (8), outage (9) etc.A pair of optical glass lens (2) and (3) are being assembled with ring-shaped step and volution (6) respectively in the two ends of lens barrel (1), by packing ring (5) sealing, form a cavity between eyeglass and the tube ring.Its center thickness can be regulated by neck bush (4), is provided with a liquid injection hole (7) at the same high level of lens barrel (1) and neck bush (4), and same low level place is provided with an outage (9), and injection optics liquid (8) in the chamber constitutes the optics of liquids lens.
Adopt this practical its advantage of parental type optics of liquids lens to be:
1. can avoid in large-scale optical glass production and the large-scale optical lens manufacture process influence and the difficulty that are caused because of physics and chemical factor.
2. the adjusting of center thickness makes to have adjustability on the structure, and the focal length of lens can be adjusted in certain scope.
3. the optics liquid of transposing different refractivity makes to have changeability in nature, and lens can obtain different light deflections.
4. the optics liquid of transposing different colours can make lens obtain different colour filter effects.
5. simple in structure, can be fit to the lens of different clear apertures, be easy to make, thereby reduced cost.
Structure of the present utility model and embodiment are described below with reference to the accompanying drawings.
Fig. 1 is the perspective view of the utility model optics of liquids lens.
Fig. 2 is the light path synoptic diagram of the utility model optics of liquids lens.
As shown in the figure, an end of lens barrel (1) is the stationary annular step, the eyeglass of packing into (2), and by neck bush (4) extruding location, neck bush (4) and lens barrel (1) adopt precision-fit; Reinstall eyeglass (3), fix by volution (6).Volution (6) and minute surface (1) adopt screw threads for fastening.Form cavity between two eyeglasses (2) and (3) and neck bush (4), its center thickness (lens thickness) is regulated and is controlled by the length of neck bush (4).Each joint all seals with packing ring (5).Be provided with a liquid injection hole (7) at lens barrel (1) and the corresponding same high level of neck bush (4), same low level place is provided with an outage (9), and injection optics liquid (8) in the chamber just can be formed this practical optics of liquids lens.
The utility model optics of liquids lens, wherein the shape of two thin optical glass mirror (2) and (3) can determine that it is protruding, flat, recessed according to different requirements, both refractive indexes also can determine structurally have adjustability according to different requirements.
The utility model optics of liquids lens, wherein the refractive index of optics liquid (8) can be changed according to different requirements with color, both can be consistent with two thin optical glass mirror (2) and (3), can also be inconsistent, have changeability in nature.
Claims (4)
1. optics of liquids lens is characterized in that these lens are made up of lens barrel (1), eyeglass (2) and (3), neck bush (4), packing ring (5), volution (6), liquid injection hole (7), optics liquid (8) and outage (9).Wherein a thin optical glass mirror (2) and (3) are being assembled with ring-shaped step and volution (6) respectively in the two ends of lens barrel (1), by packing ring (5) sealing, form a cavity between eyeglass and the tube ring, and center thickness is regulated by neck bush (4).The same high level of lens barrel (1) and neck bush (4) is provided with a liquid injection hole (7), and same low level place is provided with an outage (9), injection optics liquid (8) in the chamber.
2. optics of liquids lens according to claim 1 is characterized in that neck bush (4), fixing len (2) and regulation and control eyeglass (3).Thereby regulate the structure of lens center thickness.
3. according to the described optics of liquids lens of claim 1.2, it is characterized in that the screw threads for fastening hermetically-sealed construction of volution (6) and lens barrel (1).
4. according to claim 1,2 described optics of liquids lens, it is characterized in that lens barrel (1) and neck bush (4) are provided with the structure of liquid injection hole (7) and outage (9) at opposite position.
