The purpose of this study is to achieve maximum magnification at the smallest effective aperture while ensuring the luminous flux and resolution angle of the telescope. This telescope is the first attempt to use nano-etching technology, nano-array technology, mesoporous assembly technology, thin-film mosaic technology, and nano-optical materials to make the flatness error of the lens reach 10nm.  The luminous flux reaches 30 times that of ordinary telescopes with the same diameter. The resolution angle is 47 times that of ordinary teles
