Accompanying drawing herein is merged in specification and forms the part of this specification, show meet it is of the present utility model
Embodiment, and for explaining principle of the present utility model together with specification.
Embodiment
The utility model is described in further detail below by specific embodiment and with reference to accompanying drawing.
As shown in Figure 2-5, the utility model provides a kind of lens assembly, and lens assembly includes lens barrel 1, is arranged at lens barrel
Lens set 2 and light shield layer in 1.More precisely, light hole 11 is offered on lens barrel 1, and there is host cavity 13, lens set 2
It is contained in the host cavity 13 of lens barrel 1 with light shield layer, and light passes through lens set 2 through thus host cavity 13.Lens set 2 can be with
Including one or more eyeglass.
As Figure 2-3, lens set 2 and lens barrel 1 have first surface 21 and second surface 12 toward each other respectively, hide
Photosphere is arranged between first surface 21 and second surface 12, and the light shield layer is formed by an ink penetration.After being arranged such, work as light
When line is reflected to the position that lens barrel 1 is in contact with lens set 2, light shield layer can play a part of extinction, so as to prevent this
Light continues to propagate in lens set 2, and thereby reduces caused veiling glare in lens set 2, that is, reduces in lens assembly
Caused veiling glare, specifically as shown in the arrow in Fig. 4-5.
The first surface 21 of lens set 2 and the second surface 12 of lens barrel 1 are all the surfaces handled by delustring, by disappearing
Light processing can strengthen the extinction effect of first surface 21 and second surface 12.A kind of embodiment, delustring processing can pass through increasing
Add the roughness of first surface 21 and second surface 12 to realize.
In the embodiment shown in Fig. 4-5, preferably first surface 21 and second surface 12 are put down with the optical axis O of lens assembly
OK.After being arranged such, the assembling of lens barrel 1 and lens group 2 can be facilitated.
Further, when the quantity of eyeglass in lens set 2 is multiple, first surface 21 is formed at each eyeglass, in this feelings
Under condition, light shield layer can be provided between each first surface 21 and second surface 12.So, when light is reflected to
During the position that each eyeglass is in contact with lens barrel 1, per pass veiling glare can all be sponged by light shield layer, so that in lens set 2
Veiling glare can be reduced further.
It is known that light shield layer is formed by an ink penetration, black color can be selected according to its different extinction characteristic.
In the present embodiment, light shield layer is preferably arranged to black ink water layer.On the one hand, black ink water layer absorbing ability is better than other colors
Ink layer.On the other hand, because the main component of black ink water layer is carbon, it has stronger adhesive force, it follows that black
Ink layer and the compactness of first surface 21 and second surface 12 are higher.
Black ink water layer (light shield layer) is formed after black ink infiltration solidification, in the forming process of black ink water layer,
Brownian movement this physical phenomenon having by black ink, you can so that black ink spreads and flows into first surface 21
Between second surface 12, so as to form black ink water layer (light shield layer).
When black ink is flowed between first surface 21 and second surface 12 by way of molecule diffusion, in order to keep away
Exempt to drop to the ink between first surface 21 and second surface 12 and flow into other positions, it is preferred that the table of first surface 21 and second
Offered at least one of face 12 for a black diversion gap.
The first embodiment, as shown in figure 4, offered on first surface 21 for a first black diversion gap 211, the
One diversion gap 211 forms the first diversion groove 212 for water conservancy diversion ink with second surface 12, and the first diversion groove 212 prolongs
Extend second surface 12.
Second of embodiment, as shown in figure 5, second surface 12, which is provided with, is used for the second black diversion gap 121 of point, second
Diversion gap 121 forms the second diversion groove 122 for water conservancy diversion ink with first surface 21, and the second diversion groove 122 extends
To first surface 21.
In above two embodiment, the ink that can also to be introduced between first surface 21 and second surface 22 can
To be temporarily stored in diversion groove, without flowing at the other positions of lens set 2.
It is preferred that the present embodiment preferably uses second of embodiment, i.e., it is provided with second surface 12 and is used for the of point ink
Two diversion gaps 121, this scheme is more reasonable compared with for the mode that the first diversion gap 211 is set on first surface 21, and only
Lens barrel is processed, be more prone to manufacture and control.
Further, multiple second diversion grooves 122 can also be set, and each second diversion groove 122 is prolonged respectively
Extend a first surface 21.
In the embodiment shown in fig. 5, multiple eyeglasses are included in lens set 2, each eyeglass is arranged along optical axis O, and arrangement side
To point to the direction of image side from the thing side of lens assembly, now, each eyeglass is respectively the first eyeglass 2a, the second mirror from top to bottom
Piece 2b, the 3rd eyeglass 2c and the 4th eyeglass 2d, based on such scheme, the quantity of the second diversion gap 121 can correspondingly be set
Be set to four, i.e. open up four the second diversion gaps 121 on second surface 12, each second diversion gap 121 respectively with the first mirror
Piece 2a, the second eyeglass 2b, the 3rd eyeglass 2c, the first surface 21 on the 4th eyeglass 2d form second diversion groove respectively
122, when ink is instilled between each first surface 21 and second surface 12, each second diversion groove 122 can
Enough serve the same role, i.e. keep in ink to prevent ink from flowing at the other positions of lens set 2.
In the above description, a kind of embodiment, on optical axis O direction, the second diversion groove 122 can include
The discontinuous sub- groove of multistage, more cross-talk grooves are arranged at intervals along the contact position of lens set 2 and lens barrel 1, it follows that black ink
Water can be respectively enterd in every cross-talk groove, and is flowed into via each sub- groove between first surface 21 and second surface 12.
And in the present embodiment, the bearing of trend for being preferably provided with the second diversion groove 122 around the optical axis O of lens assembly is formed
Ring seal structure.After so setting, the second diversion groove 122 is communication type structure, and ink can instill the second diversion groove
122 any position, after ink is filled in the second diversion groove 122, you can flow rapidly into first surface 21 and second
Between surface 12.
In the embodiment shown in fig. 5, the groove in multiple second diversion grooves 122 corresponding to the first eyeglass 2a is led for son
Flow groove 122a, sub- diversion groove 122a to abut with bottom wall 122aa including bottom wall 122aa, the second eyeglass 2b, the first 2a points of eyeglass
Do not abutted with the second eyeglass 2b and second surface 12, sub- diversion groove 122aa is closed.After being arranged such, into sub- water conservancy diversion
Ink in groove 122aa is closed in the sub- diversion groove 122aa, to avoid flowing at the other positions of lens set 2.
It should be noted that bottom wall 122aa now can be used as second surface 12, the second surface 12 and second simultaneously
First surface 21 on eyeglass 2b is relative.
Under normal circumstances, lens assembly also includes light-blocking member 3, and light-blocking member 3 is used to absorb veiling glare, improves imaging matter
Amount, in the embodiment shown in Fig. 4-5, the quantity of the eyeglass in lens set 2 is multiple, and light-blocking member 3 is also arranged to accordingly
Multiple, each light-blocking member 3 is arranged between two neighboring eyeglass.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, for this
For the technical staff in field, the utility model can have various modifications and variations.It is all in the spirit and principles of the utility model
Within, any modification, equivalent substitution and improvements made etc., it should be included within the scope of protection of the utility model.
