摘要： A digital exposure apparatus includes a lens array, the lens array at least including a first lens unit and a second lens unit, a light transposition assembly arranged on an exit light path of the second lens unit, and the light transposition assembly being used for controlling a light exiting from the second lens unit to be transposed with respect to an exposure direction of the digital exposure apparatus. When the digital exposure apparatus is used for exposure, a light passing through the first lens unit and a light penetrating through the second lens unit are needed to expose the same position for multiple times.
