摘要： An imaging lens system includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens disposed in order from an object side. In the imaging lens system, the first lens has positive refractive power and an object-side surface of the first lens is concave. A field of view of the imaging lens system is 100 degrees or more. In the imaging lens system, a distance TTL from the object-side surface of the first lens to an imaging plane and a height ImgH of the imaging plane satisfy TTL/ImgH

摘要： An optical imaging system includes a plurality of fixed lenses disposed along an optical axis; a first reflective member disposed on an object side of the plurality of lenses; and a plurality of reflective members disposed on an image side of the plurality of lenses. At least one of the plurality of lenses is a variable lens having a variable focal length, and each of the plurality of reflective members is configured to move as the focal length of the variable lens changes.
