description To provide an optical imaging lens device that has an advantage of excellent imaging quality.SOLUTION: An optical imaging lens device includes a first lens group, an aperture, and a second lens group, in order from an object side to an image side along an optical axis. The first lens group includes a first optical assembly, a second optical assembly, and a third optical assembly, the first optical assembly has negative refractive power, the second optical assembly has negative refractive power, and the third optical assembly has positive refractive power. The second lens group includes a fourth optical assembly and a fifth optical assembly, the fourth optical assembly has positive refractive power, and the fifth optical assembly has positive refractive power. Two of the first optical assembly, the second optical assembly, the third optical assembly, the fourth optical assembly, and the fifth optical assembly are compound lenses formed by adhering at least two lenses, while the others are single lenses, thereby achieving the effect of high imaging quality.SELECTED DRAWING: Figure 1A 【課題】優れた結像品質の利点を有した光学結像レンズ装置を提供すること。【解決手段】光学結像レンズ装置は、光軸に沿って物体側から像側まで順に第一レンズ群、アパーチャー及び第二レンズ群を含んでいる。第一レンズ群は、第一光学アセンブリ、第二光学アセンブリ及び第三光学アセンブリを含み、第一光学アセンブリが負屈折力を有し、第二光学アセンブリが負屈折力を有し、第三光学アセンブリが正屈折力を有する。第二レンズ群は、第四光学アセンブリ及び第五光学アセンブリを含み、第四光学アセンブリが正屈折力を有し、第五光学アセンブリが正屈折力を有する。ただし、第一光学アセンブリ、第二光学アセンブリ、第三光学アセンブリ、第四光学アセンブリ及び第五光学アセンブリは、そのうちの二つが少なくとも二つのレンズを含んで粘着した複合レンズであり、残りの三つが単体レンズであることから、光学結像システムに高い結像品質の利点を有させることができる。【選択図】図1A
