Abstract
An optical apparatus includes a photosensitive diode unit, a lens and a microstructure unit. The microstructure unit is arranged between the photosensitive diode unit and the lens. After plural light beams passing through the lens are received by the microstructure unit, travelling directions of the plural light beams are changed. Consequently, at least a portion of the plural light beams is guided to the photosensitive diode unit. In such way, the light collecting efficacy of the photosensitive diode unit is enhanced.
