Abstract
An optical projection apparatus including a light source, an L-shaped projection lens, and an imaging module is provided. The light source is suitable for providing a light beam projected to a screen to form an image by the L-shaped projection lens. The imaging module is disposed between the light source and the L-shaped projection lens and is arranged on the transmission path of the light beam. In addition, the L-shaped projection lens includes a focus lens system, a zoom lens system, and a mirror, wherein the focus lens system is used to adjust the image definition, and the zoom lens system is used to adjust to the image scaling. The mirror is disposed between the focus lens system and the zoom lens system.
