ABSTRACT:
An all-reflective, relayed optical system is arranged along a beam path. The optical system includes a first mirror having positive optical power, and a second mirror having a negative optical power, wherein the second mirror receives the beam path reflected from the first mirror and wherein an intermediate image is formed after the beam path reflects from the second mirror. The optical system further includes a third mirror having positive optical power, wherein the intermediate image on the beam path is reflected from the third mirror; a fourth mirror having a negative optical power, wherein the beam path reflected by the third mirror is reflected by the fourth mirror, and a fifth mirror having positive optical power, wherein the beam path reflected by the fourth mirror is reflected by the fifth mirror to an image location.
