Cheng Zhong is generally required in lens side or the specific assembly positioning surface of reverse side processing, is needed by interferometer or centering instrument pair
Eyeglass is adjusted one by one to just.The cost and processing cost of usual system assembly are suitable, and with eyeglass in reflecting system
Quantity increase, difficulty and the different degrees of increase of cost.
To reduce the resetting difficulty of free form surface off-axis system, the overall performance of system is improved, off-axis three anti-systems having
Design scheme is by a mirror（Primary mirror）With the design of three mirrors on same blank, forms the integrated processing of combined lens and avoid two mirrors
Assembly.But there are still certain alignment errors for this form, because, in order to ensure the assembly precision of two mirrors and combined lens,
General two mirror needs to select simple spherical surface or aspherical, and needs to process positioning surface respectively on two eyeglasses.Therefore,
How free form surface off-axis system assembly cost and difficulty are reduced to the maximum extent, become off axis reflector imaging and Ultra-precision Turning
The vital task in field, the deep application for being pushed further into free form surface off-axis system have realistic meaning.
