Light emitted by a detection device is transmitted through a first compensationlens and a second compensation lens to a to-be-detected concave aspheric mirror, self alignment is performed, and then the processed light returns. The optical system selects a large incident light aperture angle and a first compensation lens bears a large aspheric normal aberration, thereby greatly improving the compensation capability; and the aspheric spherical aberration balance is realized under the condition of a small aperture ratio. The ratio of the caliber of the compensator to the caliber of the detected aspheric surface is very small and is only 0.025. With a two-piece compensatorstructure, the number of compensating lenses is small; on the basis of a full spherical design, the design limitation that a compensating system is aspheric for checking a large-caliber aspheric surface is broken through; the scheme is simple and the machining period is shorter; the image quality of an inspection light path is excellent; the wave aberration reaches a PV value superior to 0.1 lambda; and the improved Offner optical system is suitable for high-precision aspheric surface shape machining.
