Abstract: A lens module and a head mounted electronic device are provided, where the lens module includes a light emitting unit, a lens barrel, and an eye camera. The light emitting unit is disposed at an end of the lens barrel. The lens module further includes a hollow mounting stage, where the mounting stage is connected to the lens barrel, a cavity of the mounting stage communicates with an inner cavity of the lens barrel, and an optical axis of the eye camera is inclined to an axial direction of the lens barrel. The lens module helps implement an eye tracking function of VR glasses based on a folded optical path, and helps reduce impact of the eye tracking function on imaging quality of the lens module.

Abstract: A holder for a transmissive optical element is specified, having a frame and a mount for the transmissive optical element. The mount is mounted within the frame with two adjusting elements and with a guide pin arranged between the adjusting elements and its distance from the frame can be adjusted. The adjusting elements are each mounted in the frame so that they can pivot and are adjustable in their respective lengths independently of one another. The mount-side ends of the adjusting elements can each be pivoted in the mount and are attached so that they can be displaced in the longitudinal direction of the respective adjusting element. The frame-side end of the guide pin is fixed to the frame, and the frame-side end of the guide pin is pivotably mounted in the frame in the X and Y directions and slidable in the longitudinal direction of the guide pin. A method for adjusting the position of a transmissive optical element is also specified.

Abstract: An imaging lens assembly includes a lens barrel, optical lens elements, an annular retaining element and a nano-microstructure. The optical lens elements include at least one optical lens element disposed in the lens barrel. The annular retaining element is physically contacted with the optical lens element, and the annular retaining element includes an object-side surface, an image-side surface, an outer diameter surface and a light-through hole. The outer diameter surface is connected to the object-side surface and the image-side surface. The light-through hole is formed by gradually tapering from the object-side surface and the image-side surface towards the optical axis. The nano-microstructure has a plurality of irregular ridged convexes. The nano-microstructure is located between a lens barrel area defined via the lens barrel and a lens element area defined via the optical lens element on a direction vertical to the optical axis.

Abstract: An aperture unit includes a base plate, a cover, a plurality of aperture blades, a drive ring, and protrusions. The aperture blades are disposed between the base plate and the cover, and adjust the amount of light passing through by varying the size of an opening. The drive ring is disposed between the base plate and the cover, and is rotationally driven when the aperture blades are opened and closed. The protrusions are provided to the drive ring and the cover, respectively, and support the aperture blades in the direction of suppressing upward warpage of the aperture blades in a state in which the aperture blades move in the direction of reducing the size of the opening.

Abstract: A lens unit includes a jointed lens having a first optical member, a second optical member disposed on an optical axis of the first optical member, and a jointing member having a light transmissive property and disposed between the first optical member and the second optical member, and a holding mechanism configured to hold the first and second optical members. The holding mechanism holds the first and second optical members so that a distance along an optical axis direction between a first lateral surface at an opposite side to a second optical member side in the first optical member and a second lateral surface at an opposite side to a first optical member side in the second optical member becomes a preset distance. The jointing member adheres to the first optical member and the second optical member so that the distance becomes the preset distance.
