    摘要： A camera module includes a first lens assembly, a light redirecting assembly, and an image sensor. The light redirecting assembly is opposite to the first lens assembly and the image sensor. The camera module further includes a second lens assembly. The second lens assembly moves to an optical path between the first lens assembly and the image sensor or moves outside the optical path when driven by a first driving assembly. When the second lens assembly is located on the optical path, a focal length of the camera module is related to focal lengths of the first lens assembly and the second lens assembly. When the second lens assembly is located outside the optical path, a focal length of the camera module is related to a focal length of the first lens assembly.

    摘要： A reduction optical system disposed on an image side of a main optical system, a composite focal length of the main optical system and the reduction optical system being shorter than a focal length of the main optical system, includes a first lens element disposed closest to an object side and having a positive refractive power, a second lens element disposed closest to an image side and having a positive refractive power, and a positive lens and a negative lens disposed between the first lens element and the second lens element.

    摘要： A removable camera lens attachment has at least two optical elements, wherein the at least two optical elements are aligned to share an optical axis with a prime lens of the camera. The lens attachment has at least two curved surfaces. The at least two optical elements have a first surface that is conditioned to reflect a first portion of the incident light away from the image plane as reflected stray light and a second surface that is conditioned to reflect a second portion of the reflected stray light back toward the image plane to form a ghost image on an image plane of the prime lens. The lens attachment alters the effective focal length of the prime lens by no more than 15%.

    摘要： An optical device with switchable multiple lenses can be mounted on an electronic device through a connecting module, and provides finely-adjusted alignment with an image capturing lens in any position, and provides a zoom or wide-angle lens for the user to change the focal length and view field of the image. A light-filling/polarizing regulation module to fill light and eliminate unnecessary reflected light to avoid marginal diminishing effect of the image. The optical device includes a viewing device, a connecting module and a light-filling/polarizing regulation module, wherein the viewing device includes a lens module located in the housing and having at least two lenses through which an image captured by the image capturing lens is magnified. At least two lenses has the same lens power, or at least two lenses of different magnifications can be used with the switchable lens seat to obtain the effects of switching different lenses.
