    摘要: An Fθ lens for infrared large-format telecentric laser marking is disclosed, including a first lens element, a second lens element, a third lens element and a fourth lens element arranged sequentially along the propagation direction of an incident ray. The first lens element is a negative biconcave lens element including a first curved surface and a second curved surface. The second lens element is a positive meniscus lens element including a third curved surface and a fourth curved surface. The third lens element is a positive meniscus lens element including a fifth curved surface and a sixth curved surface. The fourth lens element is a plane lens adapted to play a role in protecting other lens elements. The first to third lens elements are arranged around a same axis along the propagation direction of the incident ray. The first to sixth curved surfaces are arranged sequentially along the propagation direction of the incident ray. The above Fθ lens for infrared large-format telecentric laser marking can be used as an Fθ lens for infrared laser marking, which can meet the telecentric requirement of the large-format laser marking, and control the volume of the lens within an acceptable and applicable range, to achieve miniaturizing of the whole optical system.

    摘要: A near-infrared laser focusing lens and a laser printing device are provided. The lens comprises a first lens, a second lens, a third lens, a fourth lens and a fifth lens (L1, L2, L3, L4, L5) which are coaxially arranged along a transmission direction of incident light rays, wherein the first lens (L1) is a negative plane-concave lens; the second lens and the third lens (L2, L3) are positive biconvex lenses; and the fourth lens and the fifth lens (L4, L5) are positive meniscus lenses; and a concave surface (S2) of the first lens (L1) is opposite to the second lens (L2), and the middle parts of the fourth lens and the fifth lens (L4, L5) both reversely protrude towards the transmission direction of light beams. After the shapes and the relative locations of the lenses are designed, the near infrared light can be clearly imaged, and the geometrical aberration of the lens can be effectively corrected, so as to obtain a clear flat field. In addition, because of having a large relative aperture and visual field and a long working distance, the lens is a microscope objective simultaneously having a large visual field, a large relative aperture, a long working distance and a flat field, and is capable of improving printing precision and clarity, so that the color rendition is truer and the operation is more convenient.
