Description
Technical field
The invention belongs to optical telescope technical field, be specifically related to a kind of telescope suspension type prismatic group, particularly relate to Borrow's type telescope suspension type prismatic group that a kind of structure is simple, reliability is high, good stability, optical axis are easy to adjust.
Background technology
Conventional telescope increases prism group to reduce the object of volume and upset inverted image, also referred to as erecting prism group, prism group can be divided into roof prism system (RoofPrism) (also referred to as benhain prism system) and Borrow's type prism system (PorroPrism) (also referred to as general sieve type prism system) by form difference.Because Borrow's type telescope prism group structure is simple and be easier to manufacture, also relatively more cheap in price, and than large with class ridge-roof type telescope luminous flux, contrast is high, therefore in support in end telescope and be used widely.
The telescopical two panels prism of tradition Borrow's type is fixedly installed in respectively on the erecting bed in mirror shell and forms prism group, the fine setting when adjustment of prism optical axis relies on prism to install, because mirror shell-space is narrow, higher with the Capability Requirement of adjustment personnel to the machining precision of mirror shell, namely with fixing after prism fine setting, overall optical axis fine setting after assembling only can rely on object lens adjustment, and setting range is limited; Need setting range comparatively large or later stage be out of shape, could adjust after optical axis change the needs dismounting that causes such as to collide with because of mirror shell, therefore complex structure, adjust inconvenient, efficiency is low, cost is high.Also be fixed on prism table by the binding of employing prism and form prism group (as CN2627521Y), tentatively complete the optical axis adjustment of prism, and then the position being fixed on dependence screw adjustment prism group in mirror shell is finely tuned, simplify telescope configuration, reduce the requirement to housing machining precision, also improve prism packaging efficiency.But because binding type prism group is fixed on mirror shell by screw, form elastic deformation by screw to prism table during fine setting and regulate optical axis, thus the setting range of optical axis is less; Heavily stressed and the tension force that elastic deformation adjustment can cause prism table, mirror shell, prism to put individually, thus cause prism to the adverse effect of translucidus, and the release of stress and tension force along with time lengthening, prism table deformation and the original position of optical axis deviation can be made, reduce prism group optical axis stable; Telescopical collision, vibration and make stress folded and exceed material limits, can make housing crack or be out of shape, the original position of optical axis deviation.Therefore, traditional binding type prism group setting range, reliability and stability are still not good enough.
If Borrow's type telescope prism group that a kind of structure is simple, reliability is high, good stability, optical axis are easy to adjust can be developed, it is the key solving existing Borrow's type telescope technical barrier.
Summary of the invention
The object of the present invention is to provide Borrow's type telescope suspension type prismatic group that a kind of structure is simple, reliability is high, good stability, optical axis are easy to adjust.
The object of the present invention is achieved like this, prism table, prism, pressing plate and eyepiece Connection Block, described prism is fixed on prism table respectively by pressing plate and forms erecting prism group, described prism table one end is connected with eyepiece Connection Block joint by ball screw, and described prism table is connected with eyepiece Connection Block by screw away from ball screw link.
The present invention is connected with formation joint, eyepiece Connection Block one end with the prism table of ball screw in erecting prism group, adopt plain screw to be formed away from end to be threaded, make prism group and eyepiece Connection Block form suspension type to be connected, thus reach both fixed prism group to eyepiece Connection Block, again by adjustment plain screw, reach and drive prism group to move around joint link to adjust prism optical axis, instead of adjust optical axis by the elastic deformation of prism table, therefore optical axis setting range is large, also avoid prism table, eyepiece Connection Block and prism produce harmful stress and tension force, and joint connection can also weaken the vibration of prism group, stress during impact, reduce eyepiece Connection Block, the possibility that prism table tie point cracks, there is structure simple, optical axis stable is good, the feature that reliability is high.Just can adjust prism optical axis by the screw of eyepiece Connection Block screw, particularly external head of screw to the adjustment of prism group, prism optical axis is finely tuned can carry out after mounting, is conducive to improving efficiency of assembling and reducing rework cost, is also conducive to later maintenance.
