    Abstract: A vehicle projection lens includes a plastic aspheric first lens, an aperture stop, a cemented lens consisting of a glass second lens and a glass third lens, and a glass fourth lens arranged in order from a magnified side to a minified side. An F-number of the vehicle projection lens is smaller than or equal to 0.8, and the vehicle projection lens consists essentially of four lenses respectively with positive, positive, negative and positive refractive powers.

    Abstract: An image displacement device includes a first grating and a second grating. Each grating is switchable between a diffracting state and a non-diffracting state. The first grating has a first surface and a second surface opposite the first surface, the first surface receives image beams, and the image beams leave the first grating by the second surface. The second grating is disposed downstream from the first grating in a light path and has a third surface and a fourth surface opposite the third surface. The third surface receives the image beams, and the image beams leave the second grating by the fourth surface. An exit direction of the image beam exiting the second grating is shifted a distance in a first direction from an incident direction of the image beam incident to the first grating.

    Abstract: A headlight for vehicles, including an image light source, a lens module, a lens cover, and a driving device, is provided. The lens module includes a lens assembly and an aperture. The lens assembly is disposed at downstream of an optical path of the image light source. The aperture includes a base and a movable mechanical member. The aperture is disposed at the downstream of the optical path of the image light source. The lens cover is disposed at downstream of an optical path of the aperture. The driving device is connected to the aperture. The driving device includes a power source and a linkage member connected to the movable mechanical member. The lens module includes at least two aperture values, and the aperture values are both not greater than 2.0.

    Abstract: An image displacement device includes a projection lens and a first grating. The projection lens has a lens group, and the lens group includes a first lens and a second lens, where no lens with refractive power is disposed between the first lens and the second lens. The first grating is switchable between a diffracting state and a non-diffracting state, and the first grating is disposed on one side of the first lens facing away from the second lens. A distance between the first grating and an aperture stop of the projection lens measured along an optical axis of the projection lens is smaller than a distance between the first grating and the second lens measured along the optical axis of the projection lens.

    Abstract: A zoom lens includes a first lens group with a negative refractive power, a second lens group with a positive refractive power, and an aperture stop disposed in and movable with the second lens group. Each of the first lens group and the second lens group moves individually. The zoom lens further includes a doublet lens disposed on a first side of the aperture stop and between the first lens group and the aperture stop, and at most two lenses including at least one aspheric lens are disposed on a second side of the aperture stop.

    Abstract: One embodiment of the invention provides a three-dimensional printing apparatus including a light-transmissive plate having a first surface, a platform, a support frame, a supporting seat and a rotating shaft. The platform is disposed above the light-transmissive plate, and the support frame is disposed under the light-transmissive plate. The supporting seat is disposed under the support frame and defines an accommodation space under the light-transmissive plate for accommodating an image light source. The rotating shaft pivots on a point inside or on the support frame and has a shaft center, and the shaft center is disposed under an extending plane extending from the first surface.
