It rises.For the element of constitute the objective lens and eyepiece system, bigger, the method that die casting can be used of diameter and thickness
Make non-spherical element；And the diameter and thickness of stick mirror is smaller, existing method can only be realized in optical plastic material table
Face directly processes aspheric surface, and direct processing can not be realized for optical glass material, so that the aspherical stick of glass material
Application of the mirror in rigid pipe endoscope optical system is greatly limited.Therefore, not yet occurs glass material aspheric at present
Face stick mirror element.
The content of the invention
The utility model includes a kind of aspherical glass stick mirror for rigid pipe endoscope.Wherein, glass material is aspherical
Stick mirror element is made of two one integrals and an optional part：Glass bar mirror substrate, glass aspheric lenses and glass marble
Face lens；Wherein, glass bar mirror substrate and glass aspheric lenses are the indispensable portion of the composition aspherical stick mirror element of glass material
Point, when image quality is met the requirements, this two parts is selected to form aspherical stick mirror element；Glass spherical lens is optional
Part, when image quality can not be met the requirements, it is above-mentioned it is two-part on the basis of by add glass spherical lens form it is hard
The aspherical stick mirror of pipe endoscope glass material can further improving optical system image quality.
The process of manufacture is as follows：1. it is processed respectively using existing Optical element manufacturing technique and forms rigid pipe endoscope glass material
Each part of the aspherical stick mirror of matter；2. each several part is combined as by an optical element using glued mode.
The form of the glass bar mirror substrate is that the thang-kng surface applied in existing rigid pipe endoscope optical system is spherical surface
Or the stick mirror of plane surface shape；
One of thang-kng surface of the glass aspheric lenses is aspheric surface；
Two thang-kng surfaces of the glass spherical lens are plane or spherical surface shape.
Preferably, for glass bar mirror substrate high throwing machine or classic grinding and polishing method can be used to be processed；
It is processed preferably, die casting can be used for glass aspheric lenses；
Preferably, the method that die casting or classic grinding and polishing can be used for glass spherical lens is processed；
Preferably, the glass bar mirror substrate number included in the aspherical stick mirror element of a rigid pipe endoscope glass material is
1, comprising glass aspheric lenses number for 1 or 2, comprising glass spherical surface number of lenses scope represent optical system for 0 to 4,0
In system optical system is carried out according to image quality requirement without glass spherical lens, the concrete numerical value of above-mentioned three parts with combination
It is determined after design；
Preferably, in the aspherical stick mirror element of rigid pipe endoscope glass material, it is any to carry out two glued optics members
Part surface is plane or spherical surface shape；
Preferably, the centering link in gluing procedures, usable centrescope are felt relieved, for the optics of same diameter
Element can also be identical with optical element diameter by making internal diameter tool structure, utilize radial constraint realize centering.
The utility model has the advantages that：
It is non-that the utility model by the structure of glass bar mirror substrate and glass aspheric lenses gluing realizes glass material
The aspherical stick mirror of glass material is applied in rigid pipe endoscope optical system, obtains image quality by the manufacture of spherical surface stick mirror
It is obviously improved, manufacture cost is greatly reduced, while can make to apply the stick mirror element and all glass materials of remaining optical element
The rigid pipe endoscope of matter realizes autoclave sterilization.
