Abstract

Wide field of view high resolution full transmission visible light remote sensing optical system relates to the technical field of optical system, solves the problems of existing off-axis system introducing asymmetric aberration and complex processing and adjustment, refractive system facing chromatic aberration correction problem and often being bulky, and multi-camera splicing scheme increasing system complexity and calibration difficulty, etc. The optical system comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens arranged in sequence along the optical axis and located on the same optical axis, and further comprises an aperture plane located in front of the first lens. The first lens, the second lens, the third lens, the fourth lens and the eighth lens are positive lenses, the fifth lens, the sixth lens, the seventh lens and the ninth lens are negative lenses, and a detector is arranged behind the ninth lens. The system has simple structure, extremely compressed total length, can significantly save cost and space, and has a spectral range between 400m and 750nm, and can be used for splicing wide spectral range detector.
