Abstract

An off-axis reflecting dual-band common optical path optical system is described, which integrating MWIR and VIS band. The front part is an off-axis reflecting afocal telescope, then the collimated light is splitted into MWIR and VIS band. Dual-FOV MWIR and VIS lens zoom in and out by flip in and out two lens. Comparing to other common optical path optical system, this one has the advantage of compact structure, unobstructed pupils, little chromatic aberrations, high transmittance. Good image performance is realized in dual-band optical system by CodeV analysis.
