摘要:
A fixed-focus lens capable of imaging a light valve disposed at a reduced side onto a magnified side is provided. The fixed-focus lens includes a first lens group, a second lens group, and a free form reflective mirror. The first lens group is disposed in the light path between the reduced side and the magnified side. The second lens group is disposed in the light path between the first lens group and the magnified side and includes a first free form lens. The free form reflective mirror is disposed in the light path between the second lens group and the magnified side. An imaging surface imaged from the light valve by the fixed-focus lens is a curved surface. An imaging system using the fixed-focus lens is also provided.
