Abstract
An optical imaging lens, in order from an object side to an image side along an optical axis, includes a first optical assembly, a second optical assembly, a third optical assembly, a fourth optical assembly, a fifth optical assembly, and a sixth optical assembly. The first optical assembly has positive refractive power. The fourth optical assembly has positive refractive power. The sixth optical assembly has negative refractive power. Two of the first optical assembly, the second optical assembly, the third optical assembly, the fourth optical assembly, the fifth optical assembly, and the sixth optical assembly include a compound lens with at least two lenses, while the others are a single lens, thereby providing a better optical performance of high image quality and low distortion.
