Abstract: The present disclosure discloses an optical imaging lens assembly including a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens sequentially from an object side to an image side along an optical axis. Each of the first lens and the fifth lens has a positive refractive power. Each of the second lens, the third lens, and the fourth lens has a positive refractive power or a negative refractive power. An object-side surface of the first lens and an image-side surface of the fifth lens are convex surfaces. An image-side surface of the second lens, an object-side surface of the sixth lens, and an image-side surface of the sixth lens are concave surfaces. A total effective focal length f of the optical imaging lens assembly and an entrance pupil diameter EPD of the optical imaging lens assembly satisfy: f/EPD?1.8.

Abstract: The present disclosure discloses a camera lens assembly. The camera lens assembly sequentially includes, from an object side to an image side: an alignment group, having a positive refractive power and including at least one lens, a lens closest to the object side in the alignment group having a positive refractive power; and a fixing group, having a refractive power and including at least one lens, a lens closest to the image side in the fixing group having a negative refractive power. An effective focal length fa of the alignment group and an effective focal length f of the camera lens assembly satisfy: 0.6<fa/f<2.0. The camera lens assembly of the present disclosure includes an automatic alignment group and a fixing group, which can realize the alignment function by grouping lenses, thereby improving the module process yield and shortening the AF duration.

Abstract: An example rotational flow and sink flow coupling integrated system may include a spray layer, a slurry pool, a circulating pump, a rotational flow and sink flow coupling device, and a tube bundle-type dedusting and demisting device. The rotational flow and sink flow coupling device, which includes a plurality of rotational flow and sink flow coupling units and supporting beams for supporting the rotational flow and sink flow coupling device which are located therebelow, is mounted above the slurry pool and below the spray layer. The tube bundle-type dedusting and demisting device is arranged on top of a tower body; each rotational flow and sink flow coupling unit includes a rotational flow cylinder, a rotational flow rotor, and a flow guiding device. Both the components described in this paragraph and any other additional components may be implemented in various ways according to the present disclosure.
