One housing is formed with the containing hole corresponding to described camera lens main body, and described camera lens main body is placed in the containing hole of this housing; It is characterized in that,
Described infrared ray filter is absorption infrared ray filter, and is arranged at the front end face of this camera lens main body.
Mobile phone camera lens with reduction stray light function described in the utility model, the front end face of wherein said camera lens main body further is provided with an embedding slot, and described infrared ray filter build-in is in this embedding slot.
Mobile phone camera lens with reduction stray light function described in the utility model, the outer rim of wherein said camera lens main body further is formed with external screw thread.
Mobile phone camera lens with reduction stray light function described in the utility model, the containing hole inner edge of wherein said housing further is formed with internal thread.
Mobile phone camera lens with reduction stray light function described in the utility model, the outer rim of wherein said camera lens main body further is formed with external screw thread, the containing hole inner edge of housing then further is formed with corresponding internal thread, and this camera lens main body then is bolted in the containing hole of this housing.
As mentioned above, the utility model provides a kind of mobile phone camera lens that reduces the stray light function that has, and comprising: one has the camera lens main body of front and rear end; One is arranged at the absorption infrared ray filter of this camera lens body front end face; One is formed with containing hole and this containing hole housing corresponding to the camera lens main body, and aforementioned camera lens main body is placed in the containing hole of this housing.
Unwanted whereby stray light before entering camera lens just by this infrared ray filter institute filtering, sponge, so the reduction effect of its stray light, the effect that reduces are preferable, and simultaneously this infrared ray filter are used as the protective glass of this camera lens.
Below, in conjunction with specific embodiment of the utility model and accompanying drawing thereof technical characterictic of the present utility model and technology contents are done explanation in further detail, yet, shown in accompanying drawing only for reference with explanation usefulness, be not to be used for the utility model is limited.
