The tubular portion 170 surrounds the optical axis z, and the tubular portion 170 connects the object side portion 110 and the image side portion 180 and defines an internal space 177.
請參照第1E圖,其繪示第一實施例的塑膠鏡筒100的物側za側視圖。由第1B圖至第1E圖可知,物側環面113包含溝槽結構區120,溝槽結構區120包含複數個溝槽結構,各溝槽結構為凹陷(Recessed)結構,複數個溝槽結構是以排列方式與延伸方式中至少一方式沿遠離光軸z的矢狀方向(Sagittal Direction)s設置。再者,所述排列方式是指所述複數個溝槽結構中至少二個不連續地或離散地沿遠離光軸z的矢狀方向s排列,所述延伸方式是指所述複數個溝槽結構中一個連續地沿遠離光軸z的矢狀方向s延伸。所述矢狀方向s垂直於光軸z的圓周方向(未另標號),其中圓周方向為環繞光軸z的切線方向(Tangential Direction),且矢狀方向s亦可說是遠離光軸z的矢狀方向、靠近光軸z的矢狀

Please refer to FIG. 1E, which shows a side view of the object side za of the plastic lens barrel 100 of the first embodiment. It can be seen from FIGS. 1B to 1E that the object side annular surface 113 includes a trench structure region 120, the trench structure region 120 includes a plurality of trench structures, each trench structure is a recessed structure, and a plurality of trench structures It is arranged along the sagittal direction (Sagittal Direction) s away from the optical axis z in at least one of the arrangement mode and the extension mode. Furthermore, the arrangement means that at least two of the plurality of groove structures are arranged discontinuously or discretely along the sagittal direction s away from the optical axis z, and the extension means means that the plurality of grooves are arranged discontinuously or discretely along the sagittal direction s away from the optical axis z. One of the structures extends continuously along the sagittal direction s away from the optical axis z. The sagittal direction s is perpendicular to the circumferential direction of the optical axis z (not otherwise labeled), wherein the circumferential direction is the tangential direction around the optical axis z, and the sagittal direction s can also be said to be away from the optical axis z Sagittal direction, sagittal near the optical axis z
The direction is the direction from being close to the optical axis z to the direction away from the optical axis z, from the direction away from the optical axis z to the direction close to the optical axis z, and the radiation direction of the optical axis z. In the first embodiment, the trench structure area 120 includes a plurality of trench structures, and the plurality of trench structures are specifically a plurality of straight strip-shaped groove structures 130 and a plurality of straight strip-shaped groove structures 134, each having a straight strip shape. The groove structures 130 and 134 are arranged along the sagittal direction s away from the optical axis z in an extended manner. In this way, the surface of the plastic lens barrel 100 is provided with a groove structure (in the first embodiment specifically, straight groove structures 130, 134), which can effectively reduce the reflection of non-imaging light hitting the surface of the plastic lens barrel 100 and reduce non-imaging light. The imaging light enters the imaging lens group 12 to improve the optical imaging quality.
由第1D圖可知,溝槽結構區120沿垂直光軸z的方向之長度為T,溝槽結構區120沿平行光軸z的方向之長度為L,其滿足下列條件:0.05<L/T2.0。藉此,提供大範圍的溝槽結構,以提供較佳的消除雜散光效果。另外,其可滿足下列條件:0.3<L/T1.5;或是0.05<L/T1.0。此外,其可滿足下列條件:0.3<L/T1.0。再者,參數T亦滿足條件式「T=(φ o-φ i)/2」,其中φ o為溝槽結構區120的最大外徑,φ i為溝槽結構區120的最小內徑。
It can be seen from Figure 1D that the length of the groove structure area 120 along the direction perpendicular to the optical axis z is T, and the length of the groove structure area 120 along the direction parallel to the optical axis z is L, which satisfies the following conditions: 0.05<L/T 2.0. In this way, a wide range of trench structures are provided to provide a better effect of eliminating stray light. In addition, it can meet the following conditions: 0.3<L/T 1.5; or 0.05<L/T 1.0. In addition, it can meet the following conditions: 0.3<L/T 1.0. Furthermore, the parameter T also satisfies the conditional expression “T=(φ o-φ i)/2”, where φ o is the maximum outer diameter of the trench structure area 120 and φ i is the minimum inner diameter of the trench structure area 120.
詳細而言,由第1B圖至第1E圖可知,物側環面113可更包含物側外環面114以及物側內環面115,物側內環面115較物側外環面114靠近光軸z,溝槽結構區120之至少一部分設置於物側內環面115。藉此,溝槽結構區120設置較靠近光軸z,利於減少近光軸z範圍的雜散光。第一實施例中,溝槽結構區120之一部分(即溝槽結構區120所包含的直條狀溝槽結構130)設置於物側內環面115。
In detail, it can be seen from Figures 1B to 1E that the object-side annular surface 113 may further include an object-side outer annular surface 114 and an object-side inner annular surface 115, and the object-side inner annular surface 115 is closer to the object-side outer annular surface 114 For the optical axis z, at least a part of the groove structure area 120 is disposed on the inner ring surface 115 on the object side. Thereby, the trench structure region 120 is arranged closer to the optical axis z, which is beneficial to reduce the stray light in the range of the near optical axis z. In the first embodiment, a part of the trench structure area 120 (that is, the straight groove structure 130 included in the trench structure area 120) is disposed on the inner ring surface 115 on the object side.
溝槽結構區120可設置於物側內環面115與物側外環面114。藉此,提供兩個不同角度的面(第一實施例中具體為物側內環面115與物側外環面114)上皆設置溝槽結構的可行性。第一實施例中,溝槽結構區120所包含的直條狀溝槽結構130設置於物側內環面115,溝槽結構區120所包含的直條狀溝槽結構134設置於物側外環面114,且各直條狀溝槽結構130對應並連接直條狀溝槽結構134中一者,即各直條狀溝槽結構134對應並連接直條狀溝槽結構130中一者。
The groove structure area 120 may be disposed on the object side inner ring surface 115 and the object side outer ring surface 114. In this way, the feasibility of providing groove structures on both surfaces with different angles (specifically, the object-side inner ring surface 115 and the object-side outer ring surface 114 in the first embodiment) is provided. In the first embodiment, the straight groove structure 130 included in the groove structure area 120 is disposed on the inner ring surface 115 on the object side, and the straight groove structure 134 included in the groove structure area 120 is disposed outside the object side. Each straight groove structure 130 corresponds to and connects to one of the straight groove structures 134, that is, each straight groove structure 134 corresponds to and connects to one of the straight groove structures 130.
由第1D圖可知,物側內環面115與平行光軸z的方向之夾角為α,其可滿足下列條件:35度<α<70度。藉此,可提供設置溝槽結構於特定斜度上的較佳範圍。再者,物側外環面114可垂直於光軸z,即物側外環面114的法線可平行於光軸z。
It can be seen from Figure 1D that the angle between the object side inner ring surface 115 and the direction parallel to the optical axis z is α, which can satisfy the following condition: 35 degrees<α<70 degrees. Thereby, a better range for arranging the trench structure on a specific slope can be provided. Furthermore, the object side outer ring surface 114 may be perpendicular to the optical axis z, that is, the normal line of the object side outer ring surface 114 may be parallel to the optical axis z.
由第1E圖可知,溝槽結構區120的最大外徑為φ o,塑膠鏡筒100的最大外徑為φ max,其可滿足下列條件:0.2<φ o/φ max<0.9。藉此,提供消除雜散光的較佳區域範圍。依據本發明的實施例中,參數φ o即是溝槽結構區120的通過光軸z的外徑中最大者(特別是當溝槽結構區120的外周不為正圓形時),參數φ max即是塑膠鏡筒100的通過光軸z的外徑中最大者(特別是當塑膠鏡筒100的外周不為正圓形時)。
It can be seen from Figure 1E that the maximum outer diameter of the groove structure area 120 is φ o, and the maximum outer diameter of the plastic lens barrel 100 is φ max, which can satisfy the following conditions: 0.2<φ o/φ max<0.9.
