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.

Intraoral scanner

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.

Lens and projection device

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.
