Structure so that handling ease ensures, reduces difficulty of processing, reduces processing cost；Speculum is more prone to after becoming smaller simultaneously
Ensure the face shape of mirror reflection surface.The separately machined method of multiple small reflectors, which can avoid a speculum from scrapping, to be caused
Entirety is scrapped, and improves the yield rate of speculum.The design of several small reflectors can substantially reduce weight, better meet boat
Its device loss of weight demand.Using the integrated design method of mirror unit, machining ensures speculum mounting surface coplane degree, if ensureing
Coplane degree after dry speculum bonding still ensures that good opposite position so as to ensure that after speculum and the installation of focal plane frame
It puts and coplane degree.By designing the fixture of high rigidity, ensure the speculum in mirror unit machining and speculum bonding process
The deflection of seat meets design requirement.Above-mentioned design ensure that the relative positional accuracy after speculum bonding, pass through mirror unit
Resetting difficulty is reduced after several small reflectors are linked into an integrated entity, mirror unit need to only be connected by simple screw just can be real
Existing high-precision adjustment, greatly reduces resetting difficulty, improves adjustment precision.
