Abstract
The utility model provides an elastic hydraulic varifocal lens, belonging to an optical device. Two circular optical material sheets with good elasticity and light transmission are coaxially placed, a gap is provided between the sheets, the peripheries of the sheets are sealed, the gap is connected with a pressure regulator by a thin flexible tube in which a transparent liquid with high refractive index is filled, and the pressure of the filling liquid for an eyeglass can be regulated through the pressure regulator so as to change the focal length of the lens. The elastic hydraulic varifocal lens is installed on the frame of the glasses to compose a pair of glasses capable of optionally regulating the diopter.
Description
Used optical lens, the focal length of its eyeglass is fixed; If will change lens focus, must change eyeglass or utilize suitable mechanism to move distance between each eyeglass of composition camera lens.In order to change the number of degrees of glasses, can only adopt the method for transposing eyeglass at present.For the ametropic patient of person in middle and old age, often need join two pairs of different glasses of the number of degrees and be used alternatingly, very inconvenience.
The purpose of this utility model is the shortcoming that will overcome existing optical lens focusing aspect, and a kind of camera lens is provided, and its focal length can be regulated within the specific limits continuously, but need not change the DBL travel mechanism that eyeglass also need not be traditional.
Elasticity hydraulic pressure zoom lens of the present utility model (referring to Fig. 1), two circular optical materials 1 and 2 that light transmission is good are arranged, its surface can be made flat on demand or certain dioptric curved surface is arranged, it is whippy having a slice in two at least, two coaxial placements, leave cylindrical space 3 between sheet, periphery 4 sealings.With small hose 5 space 3 is connected with pressure governor 6.In space 3, small hose 5 and pressure governor 6, be filled in the high liquid of the good refractive index of optical clarity under the service condition.Can regulate the pressure that liquid acts on 2 of sheet 1 and sheets by pressure governor 6, make sheet 1 or sheet 2 that axisymmetric deformations take place, thereby reach the purpose of regulating lens focus.
Embodiment:
The diameter that sheet is 12 is 40-60mm, and thick is 0.5-2mm, can adopt optical plastic (as polymethyl methacrylate) or organic glass to make, and wherein a slice also can select for use ordinary optical glass to make.The height in space 3 is 1mm.Periphery 4 usefulness organic siliconresins or light-sensitive emulsion GB-502 are bonding, the added metal retaining ring.Space 3, the liquid that fills in flexible pipe 5 and the pressure governor 6 can adopt saturated salt solution.
Above-mentioned elasticity hydraulic pressure zoom lens is installed in (Fig. 2) just can constitute a kind of novel glasses on the spectacle frame.The focal length of this glasses can be regulated at any time on demand, and is very convenient.
