摘要： A lens device includes a first lens module, an image sensor and a first light path turning module. The first lens module includes plurality of lenses. The first light path turning module is configured to transmit a light beam passing through the first lens module to the image sensor by exactly three or four reflections. The first light path turning module includes three or four reflecting surfaces on which the reflections occur. All the reflecting surfaces are plane surfaces. The first light path turning module includes no free form surface. All the surfaces on which the light beam is reflected are plane surfaces, wherein the plane surfaces are flat and are different from freeform surfaces.

摘要： A compensating mechanism includes a base unit, a transmission unit, an adjusting cap and a rotation setting unit. The base unit includes a grooved portion that includes a first groove and a second groove communicated with the first groove. The second groove includes a first end and a second end opposite to the first end. The first end is connected to the first groove. The first end and the second end have a height difference therebetween in an axial direction of the base unit. The transmission unit is disposed on the base unit. The adjusting cap is connected to the transmission unit. The adjusting cap drives the transmission unit to rotate when the adjusting cap is rotated. The rotation setting unit includes a movable element that is movably disposed on the transmission unit to be connected to the grooved element or to be separated from the grooved element.

摘要： A lens assembly is configured to be disposed under a cover glass, in a gap region and outside a display region, including a plurality of lenses, a reflector and an image sensor. The lenses, the reflector and the image sensor are sequentially arranged from an object side to an image side along an optical axis. One of the lenses is adjacent to the object side, has a minimum diameter of clear aperture, and has an outer circumferential portion which is non-circular. The lens assembly satisfies at least one of following conditions: BFL≥VL and BFL≥0.6×DL where BFL is a back focal length of the lens assembly, VL is a minimum side length of the image sensor, and DL is a diagonal length of the image sensor. A lens device includes a cover glass, a case, a display panel and the lens assembly.
