摘要: A projection lens including a first lens group, an aperture stop, a second lens group, and a reflective optical element sequentially arranged from a reduction side to a magnification side along an optical axis is provided. The first lens group has positive refractive power. The second lens group has negative refractive power. The reflective optical element has positive refractive power. The projection lens satisfies 1.2 2 /F 1 | 2 is an effective focal length of the reflective optical element, and F 1 is an effective focal length of the first lens group and the second lens group. A projection apparatus is also provided.
