Description
Technical field
The utility model is related to physics class, optical element or optical system, the good telescope light of espespecially a kind of flat field effect
System.
Background technology
Telescope is a kind of optical instrument that remote object is observed using lens or speculum and other optical devices, sharp
It is reflected by the concave mirror with the light refraction by lens or light and feeds them into aperture and assemble imaging, using a magnification eyepiece
And be seen, first effect of telescope is to amplify the subtended angle of distant objects, and human eye is enable to see the smaller details of angular distance clearly, is hoped
Remote second effect of mirror is the ratio pupil diameter that object lens are collected into（It is 8 millimeters maximum）Coarser light beam is sent into human eye, makes sight
Survey person can see the dark weak object that can't see originally.
With the increase of telescope multiplying power, distortion also becomes larger therewith, and how to reduce the distortion of telescope is always in industry
The direction of research.
Utility model content
For above-mentioned technical problem, the utility model provides a kind of good telescopic optical system of flat field effect, this is
System reasonable design specification, easy to use, combination and multigroup eyepiece by using half pentaprism and roof prism are effective to increase
The flat field effect of telescope.
In order to solve the above technical problems, the utility model provides a kind of good telescopic optical system of flat field effect, packet
Include the first lens of object lens, the second balsaming lens of object lens, focusing lens, half pentaprism, roof prism, the first lens of eyepiece, eyepiece
Two lens, eyepiece third lens, the 4th balsaming lens of eyepiece, the 5th lens of eyepiece, it is characterised in that：Along optical axis from left to right according to
It is secondary to be provided with the first lens of object lens, the second balsaming lens of object lens, focusing lens, half pentaprism, roof prism, the first lens of eyepiece,
The second lens of eyepiece, eyepiece third lens, the 4th balsaming lens of eyepiece, the 5th lens of eyepiece, the first lens of object lens are lenticular
Eyeglass, the second balsaming lens of object lens are falcate eyeglass, are concave surface, the first lens of object lens and object on the right side of the second balsaming lens of object lens
The second balsaming lens of mirror minimum distance be 0.5 millimeter, focusing lens be right side be concave surface falcate eyeglass, the following table of half pentaprism
Face is parallel with the upper surface of roof prism and distance therebetween is 0.8 millimeter, and the first lens of eyepiece are double concave eyeglass, mesh
The second lens of mirror be left side be concave surface falcate eyeglass, eyepiece third lens be left side be concave surface falcate eyeglass, eyepiece
It is horizontal plane on the left of 4th balsaming lens, is convex surface on the right side of the 4th balsaming lens of eyepiece, the 5th lens of eyepiece is lenticular eyeglass.
The utility model has the advantages that compared with prior art：
1st, the utility model rational Optical System Design in, using the objective lens arrangement of two groups of three-chip types, structure letter
It is single, object lens weight is effectively reduced, using half pentaprism and roof prism, the effective light path that changes reduces dispersion.
2nd, entire optical system has stronger flat field effect.
