    摘要: Provided is an interactive lens assembly, including first lens, a second lens, an aperture stop, a third lens and a filter from an object side of the interactive lens assembly to an image side of the interactive lens assembly in turn. The first lens is of a negative focal power, an image side surface of the first lens is concave; the second lens is of a focal power; the third lens is of a positive focal power, an image side surface of the third lens is convex, and each of the first lens, the second lens and the third lens is made of a plastic material; the interactive lens assembly meets the following formulas: (CT1+CT2)/CT3 -1 . CT1 represents a central thickness of the first lens, CT2 represents a central thickness of the second lens, CT3 represents a central thickness of the third lens, ImgH represents half of a length of an effective pixel region diagonal of the interactive lens assembly at an imaging surface, f represents an effective focal length of the interactive lens assembly, and TTL represents a full length of the interactive lens assembly. Meeting requirements to the above conditions is beneficial to the miniaturization and the wide-angle characteristic of the interactive lens assembly, and the interactive lens assembly has a larger field angle.

    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.

    摘要: An article comprises a lens having a width of 0.1 millimeters to 100 millimeters, a length of 0.5 millimeters to 500 millimeters, and a thickness of 0.2 millimeters to 5 millimeters; which transmits more than 60% of light having a wavelength of 760 nanometers to 2500 nanometers. The lens comprises a polymer and a colorant component. The lens is transparent and dimensionally stable at a wall thickness of 0.2 millimeters to 5.0 millimeters and remains transparent and dimensionally stable after being (a) exposed to a precondition of 60°C/60% relative humidity for 120 hours and (b) then subjected to a lead free solder test having a peak temperature of 260°C for up to 30 seconds.
