摘要： An optical imaging system includes a plurality of lenses disposed along an optical axis from an object side of the optical imaging system toward an imaging plane of the optical imaging system. The lenses are separated from each other by respective air gaps along the optical axis between the lenses. The lenses include a first lens closest to the object side of the optical imaging system. The conditional expressions 1.5 mm

摘要： An optical imaging system includes four or more lenses disposed in order from an object side. Among the lenses, a frontmost lens disposed to be closest to an object side has two or more reflective surfaces. Among the lenses, a rearmost lens disposed to be closest to an image side has an inflection point formed on at least one of an object-side surface and an image-side surface.
