Abstract
A compact optical imaging device with short optical length and low sensitivity, for use in an imaging module and an electronic device, comprises first to fifth lenses and a filter. An image-side surface of the fourth lens is convex near an optical axis of the optical imaging device. An image-side surface of the fifth lens is concave near the optical axis. The optical imaging device satisfies formulas 0.03 mm/°<TL5/FOV<0.1 mm/° and 2.4 mm<TL4/FNO<2.9 mm, TL5 being a distance from an object-side surface of the fifth lens to an image plane of the optical imaging device along the optical axis, FOV being a maximum field of view, TL4 being a distance from an object-side surface of the fourth lens to the image plane along the optical axis, and FNO being a F-number of the optical imaging device.
