Convex aspheric mirror with a large aperture is difficult to test and manufacture, here the Offner compensating method is used to test the convex aspheric mirror. In order to manufacture and test a convex aspheric mirror with a aperture of 300mm diameter , the formula of compensating system is deducted based on the third-order aberration，the initial configuration of 0ffner optical system is calculated with formula, field lens is also added to balance the aberration, then the data of initial configuration is optimized by optical software ZEMAX, the final result of Offner optical system with single compensating lens is obtained after optimization. Finally Offner optical system with double compensating lens is obtained with the same principle.

The focal length of a deformable mirror can be changed by altering its mirror profile or refractive index. With the rapid development of microelectromechanical systems technology, the variations in optical power introduced by refractive and reflective deformable mirrors have been improved, and a stabilized zoom system based on these deformable mirrors has thus become a hotspot for quick zooming and better image quality. In this paper, we discuss the domestic and foreign research on these kinds of systems, which can be divided into three categories—refractive zoom systems, all-reflective zoom systems, and catadioptric zoom systems—to indicate the differences in optical path and the deformable mirrors used. The initial theoretical layout, the verification experiment, and the performance of these systems are discussed. Above all, their characteristics and operating temperatures are highlighted, and these three types of deformable mirrors are then compared to find the possible layout for a zoom stabilization system based on two reflective deformable mirrors. Our study can help in the selection of the most suitable types of deformable mirrors and in discussions of a prototype of a stabilized zoom system. A system performance and defects radar chart for these three types of system is drawn to facilitate the selection of deformable mirrors for system design. Finally, ideas for further work to handle the challenges confronted by deformable mirrors are discussed.
