Abstract
The invention provides a refractive/diffractive hybrid type handset lens assembly, which comprises a lens assembly. The refractive/diffractive hybrid type handset lens assembly is characterized by comprising a first lens, a second lens, a third lens and an optical filter, wherein the first lens, the second lens, the third lens and the optical filter are coaxially and sequentially arranged from the object space to the image space. The first lens and the third lens are positive lenses. The second lens is a negative lens. An aperture diaphragm is positioned between the first lens and the second lens. The refractive/diffractive hybrid type handset lens assembly is reasonable in structural configuration and optimized in design. The handset lens is of a four-piece type plastic lens structure and is associated with an aspheric surface. Therefore, the number of lenses is effectively reduced. In this way, the handset lens is compact in structure and higher in cost performance.
Description
Technical field
The present invention relates to one and roll over composite mobile phone stationary lens group of spreading out, belong to mobile phone optical technical field.
Background technology
Existing 8,000,000 pixel mobile phone lens many employings 1G(Glass) 3P(Plastic), four refraction type structures of 4P and 2G2P, eyeglass number is more, and structure is comparatively complicated.Compared to refractor, diffraction lens volume is little, lightweight, dispersion characteristics are unique, design freedom is more.In imaging systems by used in combination for folding diffraction element can the aberration of corrective system further, the stuctures and properties of improvement system.
Summary of the invention
According to above-mentioned requirements, the object of this invention is to provide one and roll over composite mobile phone stationary lens group of spreading out, by rational structure model selection and optimal design, mobile lens adopts four plastic lens versions and combines with aspheric surface, effectively reduce eyeglass number, make lens construction compact, cost performance improves.
For achieving the above object, the present invention is realized by following technological means:
One rolls over composite mobile phone stationary lens group of spreading out, comprise lens combination, it is characterized in that: described lens combination comprises the first lens, the second lens, the 3rd lens and the optical filter that are coaxially arranged in order from object space to image space, described first lens, the 3rd lens are positive lens, described second lens are negative lens, and aperture diaphragm is between the first lens, the second lens.
Further:
Described first lens, the second lens and the 3rd lens are plastic aspheric lens.
Described first lens, the second lens and the 3rd lens material are respectively E48R, POLYSTYR, E48R.
The focal length 4.94mm of described lens combination.
The back work distance of described lens combination is from being greater than 0.5mm.。
The overall length of described lens combination is 5.9mm.
The invention has the beneficial effects as follows: one provided by the invention rolls over composite mobile phone stationary lens group of spreading out, by rational structure model selection and optimal design, mobile lens adopts four plastic lens versions and combines with aspheric surface, effectively reduce eyeglass number, make lens construction compact, cost performance improves.
Accompanying drawing explanation
Fig. 1 the design structural representation.
Embodiment
Below in conjunction with Figure of description, the present invention is further illustrated.
The design adopts searching patents method to select initial configuration.Then initial configuration is optimized, finally have employed Negative-Positive-Negative three plastic aspherical element eyeglasses and a slice infrared fileter.Camera lens overall length 5.93mm, back work distance, from being greater than 0.5mm, is convenient to place infrared fileter.Aperture diaphragm is positioned between first and second sheet lens, is conducive to reduction system overall length.Last a slice is infrared fileter, for reducing the noise effect of infrared light to imageing sensor.
As shown in Figure 1, one rolls over composite mobile phone stationary lens group of spreading out, comprise lens combination, it is characterized in that: described lens combination comprises the first lens 1, second lens 2, the 3rd lens 3 and the optical filter 4 that are coaxially arranged in order from object space to image space, described first lens 1, the 3rd lens 3 are positive lens, described second lens 2 are negative lens, and aperture diaphragm 5 is between the first lens 1, second lens 2.
Further:
Described first lens 1, second lens 2 and the 3rd lens 3 are plastic aspheric lens.
Described first lens 1, second lens 2 and the 3rd lens 3 material are respectively E48R, POLYSTYR, E48R.
The focal length 4.94mm of described lens combination.
The back work distance of described lens combination is from being greater than 0.5mm.。
The overall length of described lens combination is 5.9mm.
More than show and describe ultimate principle of the present invention, principal character and advantage.The technician of the industry should understand; the design is not restricted to the described embodiments; the principle that the design is just described described in above-described embodiment and instructions; under the prerequisite not departing from the design's spirit and scope; the design also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the design.The claimed scope of the design is defined by appending claims and equivalent thereof.
