Technical field
The invention belongs to ray machine adjustment fields, are related to a kind of Method of Adjustment of benhain prism racemization component optical axis.
Background technique
Benhain prism is a kind of composite prism, is made of half pentagonal prism and Schmidt prism.Benhain prism is mainly used for
Optical system disappears image rotation, and the rotation of picture caused by benhain prism is equal to twice of prism machinery rotation angle, cannot be only used for parallel
Optical path, it may also be used for non-parallel optical path.Certain type photoelectric detection equipment is using benhain prism come the image rotation that disappears, it is desirable that directional light passes through not
The depth of parallelism of emergent light and incident light is better than 20 after Chinese prism ", while guaranteeing light beam after benhain prism in convergence optical path
The bounce of picture point is less than φ 0.02mm.
It is disclosed in patent " adjustment method of benhain prism optical axis " a kind of using internal focusing telescope and comparison graticle
Benhain prism optical axis method is debugged, this method judges the graduation picture of interior focusing light pipe relative to right by eye-observation eyepiece
Than the position of graticle, human eye error is brought while increasing workload；It is in debugging benhain prism optical axis and other Chinese rib
Internal focusing telescope division line is observed by internal focusing telescope when the machinery rotation axis of mirror assembly is parallel and passes through other Chinese rib
The autocollimatic picture of mirror plane of incidence back reflection is ignored to guarantee that benhain prism optical axis is parallel with the machinery rotation axis of benhain prism component
Directional light bring deviation after benhain prism is emitted；Secondly, in debugging benhain prism optical axis and benhain prism component
It is only debugged in convergence optical path when machinery rotation overlapping of axles, bring prism angle when having ignored debugging benhain prism position
Inclination, cannot monitor in real time in parallel light path benhain prism relative to the machinery rotation axis of benhain prism component deviation to
Very big difficulty is brought to debugging.
