摘要： A projection lens configured to form an image from an image source which is disposed at an object side is provided. The projection lens includes a lens group and an aspheric mirror. The lens group has a first optical axis, and an intermediate image is formed by the lens group from the image source. The aspheric mirror has a second optical axis and an aspheric surface. The lens group is disposed between the object side and the aspheric mirror. The aspheric surface faces the lens group and reflects the intermediate image to form the image at an image side. The first optical axis is not coaxial with the second optical axis, and an offset of the image relative to the first optical axis is larger than or equal to 100%.
