Abstract: A photosensitive module is provided, for receiving light passing through a lens in an electronic device, including a base assembly, a first transparent plate, an image sensor, and a first plastic member. The base assembly includes a substrate having a main body that includes a metal material. The first transparent plate is located on the first side of the base assembly. The image sensor is located on the second side of the base assembly and adjacent to the main body, wherein the first side is opposite the second side. The substrate is disposed between the image sensor and the first transparent plate. The first plastic member is connected to the base assembly. The image sensor is surrounded by the first plastic member. When the photosensitive module receives light, the light passes through the first transparent plate and an opening of the main body sequentially to the image sensor.

Abstract: An optical system is provided, including a light source, a light shape adjusting element, a light guiding module, and a driving assembly. The light source emits a light beam in a first direction, and the light shape adjusting element changes a cross-section of the light beam from a first shape to a second shape. The light guiding module includes a base and a light guiding element connected to the base for changing the propagation direction of the light beam from the first direction to a second direction. The driving assembly drives the light guiding element to move relative to the base.
