Abstract
The utility model relates to a micro projecting and imaging lens, comprising a lens barrel (1) and a lens group arranged on the same optical axis in the lens barrel (1). The lens group comprises a plastic aspherical lens piece I (4), a spherical lens (6), a glass double-balsaming lens (8) and a plastic aspherical lens piece II (9); the plastic aspherical lens piece I (4) is arranged between protecting glass (3) and a space ring I (5); and the spherical lens (6) is arranged between the space ring I (5) and a space ring II (7). The micro projecting and imaging lens is characterized in that the glass double-balsaming lens (8) is glued by a concave mirror and a convex mirror, and the curved surface of the lens surface is a hyperbolic curved surface. The micro projecting and imaging lens has the benefits that the volume is small, the used lens pieces are less, the imaging quality is high, and the aberration elimination is high; the top end of the lens barrel is characterized in that: the upper part and the lower part are hyperbolic curved surfaces, and the left part and the right part are parallel planes, thus enabling the whole imaging lens to be more stable and firm in installation.
Description
Technical field
The utility model relates to a kind of imaging lens, particularly a kind of micro projection imaging lens.
Background technology
The kind of commercial in the market notebook, portable projector and mobile phone and function are more and more, and its volume requirement is but more and more littler, and can not satisfy its requirement because volume is excessive by the micro projection module that is embedded into commercial notebook, portable projector and mobile phone, make troubles to the manufacturer.Traditional micro projection module profile is an annular, and is loosening because of the fixing insecure camera lens that causes of its imaging lens easily when installing and using, and brings certain influence to projection quality; And the conventional lenses volume is big, and using eyeglass quantity is 7, cause production cost higher, and image quality is not high, and field of view angle is below 46 °, and aberration is bigger.
The utility model content
The utility model provides a kind of micro projection imaging lens, mainly be that traditional projection arrangement volume is big, the use eyeglass is many, image quality is not high, cost is high in order to solve, and, can cause the not high technical barrier of illumination when between imaging camera lens and the projection cloth during hypertelorism.
The utility model is for achieving the above object; the technical scheme of being taked is: a kind of micro projection imaging lens; comprise the lens combination that is arranged in lens barrel and the lens barrel on the same optical axis; described lens combination comprises: plastic aspherical element eyeglass one; spherical lens; glass cemented doublet and plastic aspherical element eyeglass two; described plastic aspherical element eyeglass one is arranged between cover glass and the spacer ring one; described spherical lens is arranged between spacer ring one and the spacer ring two; it is characterized in that: described glass cemented doublet is a concave mirror and a convex lens gummed, and the curved surface of its minute surface is the hyperbolic curve curved surface.
One end of described lens barrel is a rectangle; Its upper and lower faces is a hyperboloid, and left and right two sides is a parallel plane.
Also be provided with gland between described lens barrel and the plastic aspherical element eyeglass two.
Described plastic aspherical element eyeglass one, its minute surface are parabolic surface.
Described cover glass is an organic glass, and is fastened in the lens barrel by trim ring.
A kind of micro projection imaging lens provided by the utility model, its beneficial effect is that volume is little, the use eyeglass is few, image quality is high, illumination is high, eliminates the aberration height, the particular design on its lens barrel top: upper and lower is hyperboloid, about be parallel plane, make whole imaging lens stable more when use installing, firmly.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a right view of the present utility model
Among the figure: 1. lens barrel, 2. trim ring, 3. cover glass, 4. the plastic aspherical element eyeglass one, and 5. spacer ring one, 6. spherical lens, 7. spacer ring two, 8. glass cemented doublet, 9. the plastic aspherical element eyeglass two, 10. gland.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
As Fig. 1 and Fig. 2; a kind of micro projection imaging lens; comprise the lens combination that is arranged in lens barrel 1 and the lens barrel 1 on the same optical axis; described lens combination comprises: plastic aspherical element eyeglass 1, spherical lens 6, glass cemented doublet 8 and plastic aspherical element eyeglass 29; described plastic aspherical element eyeglass 1 is arranged between cover glass 3 and the spacer ring 1; described spherical lens 6 is arranged between spacer ring 1 and the spacer ring 27; described glass cemented doublet 8 is a concave mirror and a convex lens gummed, and the curved surface of its minute surface is the hyperbolic curve curved surface.One end of described lens barrel 1 is a rectangle, and its upper and lower faces is a hyperboloid, and left and right two sides is a parallel plane.Also be provided with gland 10 between described lens barrel 1 and the plastic aspherical element eyeglass 29.Described plastic aspherical element eyeglass 1, its minute surface are parabolic surface.Described cover glass 3 is an organic glass, and is fastened in the lens barrel 1 by trim ring 2.
Combination step of the present utility model.At first; set lens barrel; by trim ring cover glass 3 is fixed; then; described plastic aspherical element eyeglass 1 is arranged between cover glass 3 and the spacer ring 1; secondly; by spacer ring 1 plastic aspherical element eyeglass 1 and spherical lens 6 are separated; make described spherical lens 6 between spacer ring 1 and spacer ring 27; once more, spherical lens 6 and glass cemented doublet 8 are separated, make described glass cemented doublet 8 between spacer ring 27 and plastic aspherical element eyeglass 29 by spacer ring 27; at last, by gland 10 all eyeglasses are fixed in the lens barrel 1.
Its beneficial effect be volume little, use that eyeglass is few, image quality is high, illumination is high, eliminate the aberration height, the particular design on its lens barrel top: upper and lower be hyperboloid, about be parallel plane, make whole imaging lens use when installing more stablize, firm.
