    Abstract: A lens module with enhanced absorption of stray light includes a sensor and a mounting bracket. The sensor includes a photosensitive area and a non-photosensitive area arranged surrounding the photosensitive area. The sensor is received in the mounting bracket and a window is defined in the mounting bracket. An annular flange extends from an inner wall of the window towards a center axis of the window. The annular flange includes a reflecting surface facing away from the inner wall of the window and tilted towards the sensor. The photosensitive area is exposed in a through hole of the annular flange. Diffusing reflection structures are formed on the reflecting surface and are configured to diffuse light incident on the non-photosensitive area away from the photosensitive area.

    Abstract: A 3D sensing device includes a base, an infrared emitting module, a first infrared receiver, a second infrared receiver, a color camera module, a first moving member, a second moving member, a first driving member, and a second driving member. The first moving member and the second moving member are slidably mounted on the base. The first driving member and the second riving member respectively drive the first moving member and the second moving member to slide along the base. The infrared emitting module is mounted on the first moving member. The color camera module is located between the first infrared receiver and the infrared emitter. The second infrared receiver is mounted on the second moving member. The first moving member and the second moving member respectively move the infrared emitting module and the second infrared receiver along the base relative to the first infrared receiver.

    Abstract: A holder for a camera module includes first and second surfaces, an optical filter receiving groove is recessed from the first surface to the second surface to form a step portion and a glue receiving portions extend from angled abutments of the step portion. A sensor receiving groove is recessed from the second surface to the first surface, and the sensor receiving groove communicates with the optical filter receiving groove. At least one escape passage is defined in the holder, the at least one escape passage communicates with the optical filter receiving groove and the sensor receiving groove. The at least one escape passage abuts the glue receiving portions and provides an escape path for captured moisture and gases expanding or shrinking because of temperature variations.

    Abstract: A optical projector device less vulnerable to deformation of projected light by generated heat includes a printed circuit board, a light source, and an optical module. The heat-generating light source emits a laser beam, the optical module being mounted on the printed circuit board and surrounding the light source. The optical module comprises a lens holder, a collimating optical element received in the lens holder, and a diffractive optical element away from the light source. The lens holder comprises an outer lens holder and an inner lens holder fixed in the outer lens holder, and the diffractive optical element is received in the inner lens holder, this arrangement enables the dissipation of any heat-expansion force away from these elements.

    Abstract: A lens module with physically stronger foundations and enhanced stability includes a circuit board, an image sensor thereon, a mounting bracket, an optical filter, and a lens unit. The mounting bracket is connected to the surface of the circuit board which has the image sensor. The optical filter is connected to mounting bracket and positioned above the image sensor. The lens unit is connected to the mounting bracket facing away from the circuit board through a frame of adhesive. The surface of the lens unit connected to the mounting bracket has protrusions which are positioned at inner edges of the adhesive layer. The protrusions are taller than the depth of the adhesive layer.
