Technical field
The utility model is related to physics class, optical element or optical system, espespecially a kind of modified telescopic optical 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 development of telescope technology, how to simplify mirror structure to meet design requirement, be always industry development
Key technology.
