An illumination assembly includes one or more light sources and an optical assembly. The one or more light sources is configured to provide illumination light. The optical assembly includes a first optical component, a second optical component, and a third optical component. The first optical component, the second optical component, and the third optical component are positioned so that the illumination light is (i) received by the first optical component, (ii) transmitted through the first optical component toward the second optical component, (iii) reflected at the second optical component toward the third optical component, (iv) reflected at the third optical component toward the second optical component, and (v) transmitted through the second optical component. A method of providing illumination using an optical assembly is also disclosed.
