![]() Sorry to disappoint you, but Johns Hopkins University had nothing to do with this, and there was no “study”. Those unfamiliar with optics would likely be quite impressed by all this. The Facebook ad included slick video showing this marvelous device zooming in on someone’s face from miles away, as well as a close-up shot of the moon (actually an Apollo shot of the back side of the moon!) and planets. This is the first monocular to achieve this magnification and clarity on such a small scale. ![]() The maximum magnification reached is 300 times. The resolution angle is 47 times that of ordinary telescopes with the same diameter. The luminous flux reaches 30 times that of ordinary telescopes with the same diameter. 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 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. Here’s the ad copy- The telescope was invented by Johns Hopkins University and released on July 1 (2020). ![]() Knowing the ad was pure BS, we blew $80 on one just so we could do a factual review, and save you from wasting your hard-earned dollars on garbage. But recent ads for a “4K 10-300x40mm Super Telephoto Zoom Monocular Telescope”, also on Facebook, take fraudulent advertising to a whole new level! We received several calls from customers asking if we carried these things, and someone even drove to our office to see if we might have them. One of the biggest scams we’ve ever seen in the optics biz was the “ Rated #1 Best Nightvision High Powered Waterproof Binoculars” promoted on Facebook.
