However, catadioptric systems suffer from limitations such as a narrow field of view, significant central obscuration, and alignment complexity, while transmissive systems require elaborate compensation mechanisms to correct astigmatism induced by the axial deviation from parallel-plate beam splitters. To address these challenges, this paper presents a large-aperture, wide-field-of-view transmissive infrared-laser dual-band optical system based on harmonic diffraction. The system shares a front group of two lenses for both infrared and laser channels, with a 45\u00b0 beam splitter directing light into separate paths. A harmonic diffractive surface is introduced in the infrared channel to correct astigmatism caused by the beam splitter, achieving high-quality imaging over an 8.3\n                    <jats:sup>\u2218<\/jats:sup>\n                    \u00d77\n                    <jats:sup>\u2218<\/jats:sup>\n                    field of view with a total length of less than 108\u00a0mm under a 52\u00a0mm aperture.
