The lens group is disposed in the accommodation cavity and is supported on the bearing surface.

Abstract: A light source module includes a casing, a first light source disposed in the casing to emit a first light, a first semi-transparent and semi-reflective mirror disposed in the casing and located on an optical path of the first light, and a heat dissipation member disposed in the casing and located on a second axis of the first semi-transparent and semi-reflective mirror. A first part of the first light passes through the first semi-transparent and semi-reflective mirror or is reflected by the first semi-transparent and semi-reflective mirror and then travels along a first axis. A second part of the first light is reflected by the first semi-transparent and semi-reflective mirror or passes through the first semi-transparent and semi-reflective mirror and then travels along a second axis. The first part is more than the second part. The second part of the first light is directed to the heat dissipation member.

Abstract: An external electric adjusting module adapted for being externally connected to a lens includes a bracket including a first positioning portion, a gear set, a driving assembly driving the gear set to operate, and a variable resistance rotating member. The gear set is rotatably disposed on the bracket, is adapted for being externally connected to the lens, and includes a second positioning portion, a rotating shaft, and a first driving portion located on the rotating shaft. The variable resistance rotating member is sleeved on the rotating shaft, is electrically connected to the driving assembly, and includes a second driving portion corresponding to the first driving portion to be linked with the rotating shaft. When the gear set is located at an initial position together with the lens, the first and second positioning portions are aligned with each other, and the second driving portion abuts against the first driving portion.

Abstract: An optical module includes a base, a holding component, an optical element, and at least one detachable structure. The holding component is disposed on the base, in which a position of the holding component relative to the base along a first axial direction is adjustable. The optical element is disposed on the holding component. The detachable structure is extended from one of the base and the holding component to face another one of the base and the holding component, so as to limit a position of the holding component relative to the base along a second axial direction.

Abstract: An intraoral scanner includes a projecting module, an image-capturing module, a linkage structure, and a manipulation part. The projecting module includes a first lens device and a light source. Light emitted by the light source is projected out of the intraoral scanner by the first lens device. The image-capturing module includes a second lens device and an image sensor. The image sensor receives the light from the outside of the intraoral scanner through the second lens device. The manipulation part is exposed from the intraoral scanner and is mechanically linked with the first or second lens device through the linkage structure. Therein, the manipulation part is operable to correspondingly move at least one first lens of the first lens device or at least one second lens of the second lens device through the linkage structure, so as to adjust a scanning zone of the intraoral scanner.

Abstract: A lens includes a casing, a first lens group, a second lens group and a heat dissipating member. The first lens group is disposed in the casing and close to a first side of the casing. The second lens group is disposed in the casing and close to a second side of the casing, wherein the first side is opposite to the second side. The heat dissipating member is disposed at the second side of the casing and contacts the casing.

Abstract: An optical engine module includes a casing, a bracket, a light pipe, a cover and a resilient member. The casing has an accommodating space and a baffle, wherein the baffle is located in the accommodating space. A first end of the bracket has at least one first block portion, the bracket is disposed in the accommodating space, and a second end of the bracket is oriented towards the baffle, wherein the first end is opposite to the second end. The light pipe is disposed in the bracket and abuts against the at least one first block portion. The cover is disposed on the second end of the bracket and abuts against the baffle. The resilient member is configured to generate an elastic force to push the bracket towards the baffle.

Abstract: The invention discloses a lens adjusting module for adjusting the position of a lens module. The lens adjusting module includes an input rod and an output rod, wherein the input rod is configured along a first direction and has an inclined surface. The output rod is configured along a second direction perpendicular to the first direction. The output rod has a first contact surface contacting the inclined surface, and a second contact surface contacting the lens module. When the input rod moves along the first direction, the first contact surface of the output rod moves along the inclined surface of the input rod, and the lens module moves with the output rod along the second direction.
