摘要： A camera module includes an imaging lens assembly, an image sensor, a plate element and a polarizing element. The imaging lens assembly is configured to define an optical axis. The image sensor is disposed on an image surface of the imaging lens assembly. The plate element is farther from the image sensor than the imaging lens assembly from the image sensor on the optical axis, wherein the plate element is inclined to the optical axis. The polarizing element is disposed on an image side of the plate element, so that an object-side light with a specific polarity from the plate element passes through.

摘要： A variable aperture module includes a blade assembly including movable blades, a positioning element including positioning structures and a driving part including a rotation element. The movable blades are disposed around an optical axis to form a light passable hole with adjustable size for different hole size states and each have an inner surface to define the contour of the light passable hole in each hole size state. The positioning structures correspond to the movable blades. The rotation element is rotatable with respect to the positioning element and is configured to rotate the movable blades to adjust a size of the light passable hole. There are matte structures disposed on each inner surface. Each matte structure is single structure extending towards the optical axis, such that at least part of the contour of the light passable hole has an undulating shape at least in several hole size states.

摘要： An optical system includes an image surface, an aperture stop, a first and a second quarter-wave plate, a partial reflector, a reflective polarizer, a first and a second optical lens element. The image surface and the aperture stop are respectively at a front side and a rear side of the optical system. The first quarter-wave plate is between the image surface and the aperture stop. The partial reflector between the first quarter-wave plate and the aperture stop has an average light reflectivity of 35%. The second quarter-wave plate is between the partial reflector and the aperture stop. The reflective polarizer is between the second quarter-wave plate and the aperture stop. The first optical lens element between the image surface and the aperture stop has a convex front-side surface. The second optical lens element between the first optical lens element and the aperture stop has a concave rear-side surface.
