[specific embodiment]
The utility model is described in further detail below by specific embodiment combination Fig. 1, Fig. 2 and Fig. 3, so as to
The advantages of better understood when the embodiment of the utility model and its various aspects.Below in an example, following tool is provided
The purpose of body embodiment is easy for becoming apparent from present disclosure thorough explanation, rather than to the limit of the utility model
System.Wherein the words of the indicating positions such as upper and lower, left and right is only for shown structure in the accompanying drawings position.
As depicted in figs. 1 and 2, the utility model embodiment provides a kind of barn door 10.The barn door 10 is in hollow and annular
Structure, barn door include object side 11, the image side surface 12 being oppositely arranged with object side 11 and attachment side 11 and image side surface
12 side wall, side wall include the medial surface 13 and the lateral surface 14 that is oppositely arranged with medial surface close to optical axis 21, on barn door 10
Equipped with light-absorption layer 1321, light-absorption layer 1321 forms honeycomb by several pits.
Light outside lens barrel is incident in lens barrel from the object side of lens barrel via the light hole on barrel, and extraneous light enters mirror
It will appear reflex on barn door after in cylinder.In the present embodiment, light-absorption layer 1321 is provided on barn door, it can be with
The reflex for effectively cutting down the light being incident on barn door generates the veiling glare of interference by absorbing to imaging effect, it is therefore prevented that
Image quality is effectively promoted to effectively weaken the veiling glare phenomenon inside lens assembly in the further reflection of light.
In the utility model embodiment, light-absorption layer 1321 is formed by 3 D-printing.
As shown in Fig. 2, being provided with light-absorption layer 1321 on medial surface 13, specifically, medial surface 13 includes leaning on from object side 11
First surface 131 that the edge of dipped beam axis extends towards image side bending, from the edge of the separate object side 11 of first surface 131 towards remote
The second surface 132 that extends from the direction of optical axis and from the edge of separate the optical axis of second surface 132 towards the side of separate optical axis
The third surface 133 extended to inclination.Wherein, above-mentioned light-absorption layer 1321 is provided on second surface 132 and third surface 133.
But light-absorption layer 1321 also in practical applications, can be set on first surface 131, be irradiated to the surface on different directions to absorb
On veiling glare, enhancing cut down veiling glare energy effect.The light incident direction of veiling glare is as shown in line segment with the arrow in Fig. 2.
In addition, above-mentioned light-absorption layer 1321 can be set on object side 11 and image side surface 12, also to advanced optimize to miscellaneous
The assimilation effect of light.
