Abstract
The invention discloses a camera lens which comprises a lens barrel (I). The lens barrel (I) is internally provided with a plurality of lenses. The lenses comprise a glass spherical lens (21) and plastic aspheric lenses (22). Insulators (3) for separating the glass spherical lens (21) and the plastic aspheric lenses (22) are arranged between the glass spherical lens and the plastic aspheric lenses. Two surfaces, which face the glass spherical lens (21), of the insulators are planes. The glass spherical lens (21) is provided with lens planes (21a) which abut against the planes on the insulators (3) for forming a planar abutting structure by the glass spherical lens (21) and the insulators (3). The camera lens has advantages of simple structure, convenient assembling and high imaging quality.
Description
[technical field]
The present invention relates to a kind of camera lens.
[background technology]
In current camera lens, generally all comprise plastic cement aspherical lens and glass spheric glass, plastic cementAspherical lens and glass spheric glass generally adopt metal spacer ring or light-shielding sheet to separate. Owing to mouldingGlue aspherical lens can be in its peripheral one-shot forming plane in the time of injection molding moulding, therefore,Plastic cement aspherical lens is plane with contacting of plastic cement aspherical lens, metal spacer ring or light-shielding sheetContact, thus make plastic cement aspherical lens can not produce inclination. But the one-tenth of glass spheric glassType process complexity can not contact with metal spacer ring or light-shielding sheet in the process of moulding in one-shot formingPlane, so in camera lens in the market, glass spheric glass and metal spacer ring or shadingThe contact of paper is all that (sphere of glass spheric glass and metal spacer ring or light-shielding sheet are straight for sphere-contactContact), also referred to as being sphere breasting. And sphere and metal spacer ring or light-shielding sheet are in breastingTime all can occur glass spheric glass tilt existing picture. Glass spheric glass is at lens erectionTime the flatness and the optical axis that are difficult to the whole arrangement of mirrors head of guarantee group after vertical are positioned to center, thereby makeBecome the solution of whole camera lens as bad, and in the time that camera lens carries out environmental testing, fall through vibrationGlass spheric glass on the breasting face that contacts with metal spacer ring or light-shielding sheet also may causeMake a variation and affect environmental testing. Therefore, in conventional lenses glass spheric glass and metal spacer ring orThe sphere breasting of light-shielding sheet has a strong impact on product percent of pass, and entreprise cost is increased.
[summary of the invention]
The present invention seeks to have overcome the deficiencies in the prior art, provide a kind of simple in structure, group is verticalConvenient, the camera lens that image quality is high.
The present invention is achieved by the following technical solutions:
A kind of camera lens, comprises lens barrel, is provided with multi-disc lens, described lens in described lens barrelComprise glass spheric glass and plastic cement aspherical lens, described glass spheric glass and plastic cement are non-Between spheric glass, be provided with the separator for separating the two, it is characterized in that: described isolationThe two sides that part is relative with glass spheric glass is plane, and described glass spheric glass is provided withThereby directly fit and make glass spheric glass and separator form plane with the plane on separatorThe eyeglass plane of supporting structure.
Camera lens as above, is characterized in that: described eyeglass plane is ground from glass for passing throughOne side direction opposite side of glass spheric glass sinks and the step surface of formation.
Camera lens as above, is characterized in that: described separator is metal spacer ring.
Camera lens as above, is characterized in that: described separator is light-shielding sheet.
Compared with prior art, the present invention has the following advantages:
1, the two sides that separator of the present invention is relative with glass spheric glass is plane, andThereby glass spheric glass be provided with separator on plane directly laminating make glass spherical mirrorSheet and separator form the eyeglass plane of plane supporting structure. Employee can be very in the time of the vertical camera lens of groupMake easily the eyeglass plane of glass spheric glass and the laminating of the plane of separator, can not make glassThere is the situation of inclination in spheric glass, has reduced camera lens solution and occurred as bad situation, thereby carriedRate of good quality rate, has also improved production efficiency, reduces costs; Camera lens is in the time of environmental testing in addition,The eyeglass plane of the glass spheric glass falling through vibration also there will not be distortion, such mirrorThe resolution of head after environmental testing can be still good, thereby increase making of camera lens after sellingLife-span used time.
2, eyeglass plane of the present invention is another from a side direction of glass spheric glass by grindingOne side is sunk and the step surface of formation. By grind can be easily at the glass marble of script sphereOn face eyeglass, grind a step surface, processing technology is simple, and precision is high.
3, the present invention is simple in structure, practical, is applicable to applying.
[brief description of the drawings]
Fig. 1 is that in currently available technology, glass spheric glass and separator are showing of sphere breastingIntention;
Fig. 2 is the schematic diagram that glass spheric glass of the present invention and separator are plane breasting.
[detailed description of the invention]
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 2, a kind of camera lens, comprises lens barrel 1, in described lens barrel 1, is provided with multi-discLens, described lens comprise glass marble face eyeglass 21 and plastic cement aspherical lens 22, described inGlass spheric glass 21 and plastic cement aspherical lens 22 between be provided with for separate the two everyFrom part 3, described separator 3 is metal spacer ring or light-shielding sheet. Described separator 3 withThe two sides that glass spheric glass 21 is relative is plane, on described glass spheric glass 21, establishesThereby have with separator 3 on plane directly laminating make glass spheric glass 21 and separator 3Form the eyeglass plane 21a of plane supporting structure. Employee can be easily in the time of the vertical camera lens of groupMake the eyeglass plane 21a of glass spheric glass 21 and the laminating of the plane of separator 3, thereby makeGlass spheric glass 21 there will not be the situation of inclination, has reduced camera lens solution as bad situationOccur, thereby improve yields, also improved production efficiency, reduce costs; Camera lens exists in additionWhen environmental testing, through the eyeglass plane 21a of the glass spheric glass 21 that falls of vibration also notThere will be distortion, the resolution of such camera lens after environmental testing can be still good, therebyLife-span while increasing the use of camera lens after selling.
Described eyeglass plane 21a is another from a side direction of glass spheric glass 21 by grindingOne side is sunk and the step surface of formation. By grind can be easily at the glass marble of script sphereOn face eyeglass 21, grind a step surface, processing technology is simple, and precision is high.
