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 telescopes with the same diameter. The maximum magnification reached 300 times.This is the first monocular to achieve this magnification and clarity on such a small scale.
①.Twist-up eyecup to adjust: Adjust eyepiece to raise the cup to appropriate height. (Keep the eyes and eyepiece lenses at the best distance to prevent the eyes get blurry lens)
②.Focus adjustment: Eyes close to the eyepiece, the objective lens at the target scene, and then the telescopic lens tube completely pulled out, clockwise slowly turn the focus handwheel until you see a clear target so far.
③.Zoom adjustment: Slowly adjust the magnification adjustment ring. Adjust the required magnification, and then fine-tune the focus hand wheel, until the target becomes clear so far.
