    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 projection lens provided is for projecting an image beam. The projection lens is disposed on a transmission path of the image beam and includes a first group of lenses and a second group of lenses. The first group of lenses includes a first spherical lens and a first aspheric lens. After the image beam passes through the first group of lenses, an intermediate image is formed between the first group of lenses and the second group of lenses, in which the first aspheric lens is the lens in the first group of lenses closest to the second group of lenses. A projection device using the projection lens is also provided. The projection device further includes a planar reflector on the transmission path of the image beam.

    摘要: An optical module including a first integration rod, a polarization beam splitting unit, a first reflector, a first quarter-wave plate, and a light source is provided. The first integration rod has a first end and a second end opposite to each other. The polarization beam splitting unit is disposed at a side of the first end. The polarization beam splitting unit reflects a beam with a first polarization direction and allows a beam with a second polarization direction to pass through. The first reflector is disposed at a side of the second end. The first quarter-wave plate is disposed between the polarization beam splitting unit and the first reflector. The light source provides a light beam to the polarization beam splitting unit. The light beam includes a first polarization beam with the first polarization direction. The polarization beam splitting unit reflects the first polarization beam to the first integration rod.
