Abstract: A lens assembly includes a first lens group, a second lens group, a third lens group, a fourth lens group, and a reflective element. The first lens group is with refractive power. The second lens group is with positive refractive power. The third lens group is with positive refractive power. The fourth lens group is with refractive power. The reflective element includes a reflective surface. A light from an object sequentially passes through the first lens group, the second lens group, the third lens group, and the fourth lens group to an image side along an axis. The reflective element is disposed between an object side and the image side along the axis. Intervals of the lens groups are changeable when the lens assembly zooms from a wide-angle end to a telephoto end.

Abstract: A 3D printing apparatus includes a consumable spool for winding a consumable. A consumable rewinding device includes: a driving assembly including a driving portion and a rotating shaft, the driving portion being connected to the rotating shaft for providing power to drive the rotating shaft to rotate; and a roller for bearing a consumable spool, the rotating shaft is connected to the roller, and when the rotating shaft drives the roller to rotate, the consumable spool is driven to rotate by a frictional force between the roller and the consumable spool. The 3D printing apparatus and the consumable rewinding device enable the consumable to be rewound around the consumable spool, avoiding the problem of printer jamming due to messy distribution of the consumable, have a simple structure, and is easy to implement.
Abstract: A method for preparing a double-sided microlens array, which is used to prepare a uniform, large-area and easy-to-control microlens array on upper and lower surfaces of a sapphire glass lens. A complete laser wavefront is spatially divided into many tiny parts, and each part is focused on the focal plane by a corresponding small lens, and the light spots are overlapped to achieve uniform light in a specific area. The sapphire glass lens is applied to the deep ultraviolet LED inorganic module packaging device to reduce the total reflection loss between the deep ultraviolet LED package optical window-air interface, and focus the light passing through the lens on the focal plane, while increasing the emission of light Coupling ability, uniform light intensity of ultraviolet LED.
