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: 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 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: 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.
