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%.

摘要： A beam combiner for combining a first color beam, a second color beam, and a third color beam is provided. The beam combiner has a transparent substrate with a first optical surface on which a first reflective film reflecting the first color beam is disposed, and a second optical surface on which a second reflective film reflecting the second color beam is disposed. The first optical surface and the second optical surface are parallel. The second color beam entering the transparent substrate is reflected by the second reflective film and leaves the transparent substrate by passing through the first optical surface, while the third color beam enters the transparent substrate from the second optical surface and leaves the transparent substrate by passing through the first optical surface. The optical paths of the first, the second, and the third color beam are substantially coincident after emerging from the first optical surface.
