摘要： A focusing device comprises a base unit and a mirror unit which is translatable relative to the base unit parallel to an optical axis of the focusing device. The mirror unit is configured to receive incident light along the optical axis in a first direction and to reflect the incident light parallel with the optical axis in said first direction. The mirror unit comprises at least four mirrors, at least one of the mirrors being curved.

摘要： An optical telescope may include an array of optical lenslets in a common plane, and optical waveguides extending from respective optical lenslets and each having a common optical path delay. Further, at least one optical star coupler may be downstream from the optical waveguides, and an optical detector may be downstream from the at least one optical star coupler and having an optical image formed thereon.

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.
