Description
Technical field
The utility model is related to a kind of optical element, more particularly to a kind of anti-dazzling screen and the imaging lens with the anti-dazzling screen
Group.
Background technology
With the development of electronic device industry, increasing application needs imaging device to aid in, so as to complete more
Complicated function is in order to lifting the performance and service quality of application product in field.
Camera lens module includes a lens barrel, one group of lens group being assembled in the lens barrel and an anti-dazzling screen.Anti-dazzling screen
Effect be for adjusting luminous flux in optical system, when ambient enter camera lens when, can via anti-dazzling screen between the lenses
Stop that unwanted light is entered.Common anti-dazzling screen in the mobile lens of prior art, is that a thin rounded flakes one printing opacity of band is worn
The structure in hole, and printing opacity perforation interior side-wall surface is all without any process.When light is radiated at the section of anti-dazzling screen printing opacity perforation
When, it can be interfered from fault plane reflection and the light of diffusion to optical system, and these veiling glares can be produced in lens imaging face
The unnecessary image such as ghost or solar flare.Early stage Lens are larger, anti-dazzling screen section thickness more than lens length hour, these
The impact of veiling glare is not notable, but is when anti-dazzling screen thickness accounting is improved, to be especially used in thin type cell phone when lens length reduces
It is just particularly significant in the ghost and solar flare phenomenon of imaging surface during camera lens.In addition, if in the loophole interior side-wall surface of anti-dazzling screen
Coating delustring paint, although this mode can solve the problems, such as that loophole madial wall is reflective, which task difficulty is big, performance
It is unstable, and need larger cost.Therefore, the spuious optical phenomenon that anti-dazzling screen section causes how is improved just critically important.
The utility model is researched and proposed for the deficiencies in the prior art.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of anti-dazzling screen, can efficiently reduce spuious optical phenomenon.
Anti-dazzling screen of the present utility model, is installed in inside camera lens, and it includes one piece of circular light-transmitting plate, the anti-dazzling screen tool
The first face for having relative and the first parallel face and the second face, the anti-dazzling screen has a transparent area and around the transparent area
Shading region.
Further, all transparent areas in the second face of the anti-dazzling screen or with a transparent area and in the transparent area
The shading region of surrounding.
Further, projection plane of the transparent area in the face of the anti-dazzling screen first on the face of the anti-dazzling screen second, completely
It is included by the transparent area in the face of the anti-dazzling screen second.
Further, the transparent area surface in the face of the anti-dazzling screen first coats functional filter coating, the function filter coating choosing
One kind from infrared cut of light filter coating, ultraviolet light cut-off light filtering films, low pass filter coating, anti-reflection film.
Further, the transparent area surface in the face of the anti-dazzling screen second coats functional filter coating, the function filter coating choosing
One kind from infrared cut of light filter coating, ultraviolet light cut-off light filtering films, low pass filter coating, anti-reflection film.
A kind of imaging lens group, comprising a lens barrel, one group of lens group being assembled in the lens barrel and an anti-dazzling screen, its
It is characterised by, the anti-dazzling screen is any of the above-described anti-dazzling screen.
Compared with prior art, the beneficial effect of the utility model generation is：
Middle light hole of the present utility model is solid, and light shield layer is covered on circular light-transmitting plate by one layer
Black matt coating is realizing shaded effect.So effectively anti-dazzling screen section thickness can be preferably minimized, black matt plating
The thickness of layer effectively reduces reflection and diffusion that incident ray is produced in section, so as to substantially reduce generally in micron level
Spuious optical phenomenon.
