Abstract: The invention provides an optical device. The optical device includes an image capture unit, at least one light emitting device, and a light conductor. The light conductor defines a space above a substrate on which the image capture unit is disposed. The light conductor includes a central portion and a surrounding portion. The central portion is disposed above the space and has a first surface relatively far from the image capture unit and a second surface opposite to the first surface and relatively close to the image capture unit. The surrounding portion is connected to the central portion and surrounding the space. The surrounding portion includes a reflection surface connected to the first surface and tilted at an angle toward the image capture unit with respect to a plane of the first surface. The reflection surface is adapted to perform total reflection.
