Traditional adjusting methods can not meet image quality requirements of middle and high-end lens. Fine adjustment based on centering instrument is popular because this method can bring high image quality for lens. Akind of design of precision reflective centering instrument is introduced in this paper，including the design theory and its technologies，such as collimating objective，reference turntable，lifting platform and equipment display and control. The designexamples areintroduced，includingcollimatingobjective，precisionrotor，electriclifttableand displayandcontrol module. The coaxiality of each lens reaches 2 μm. The experiments show that using this method of this paper can design a nicecenteringinstrument，andthecenteringinstrumentcanbeappliedintheadjustmentofhigh-endlenswhichrequirehigh imagequality.Inaddition，assemblyefficiencycanbeimproved，too.
