Smartphone cameras are pretty amazing, except for capturing long-distance shots. The cast-aluminum Nocs Provisions Photo Rig Adapter is a handy pocket pal that clamps on to align a phone lens to a Zoom Tube Monocular Telescope or standard binoculars for true analog zoom photos and videos.
The ultra-compact, all-weather Zoom Tube has best-in-class optics and a wide field of view to bring nature closer. Really close. An optional 4x multiplier lens turns it into a field microscope. Weighing just 9.5 oz., it easily slides into a pocket, and the awesomely rugged, grippy, water-resistant ribbed housing absorbs impact.
Engineer Matt Ferraro came up with an innovative method to hide images in clear acrylic. At first glance, the tile appears to be completely transparent, but when light passes through it onto a surface, an image is revealed. The technique relies on caustic patterns which cast shadows and transmit light at varying intensities.
YouTube science channel Journey to the Microcosmos showcases astounding close-up images of the tiniest organisms on Earth. In this video, Hank Green looks back at their first four seasons, and celebrates with a set of new tools for Master of Microscopes James Weiss.
Now that The Action Lab has painted a room in the blackest and glowing-ist paints, he’s renovated his temporary space again. This time, he covered its walls, ceiling, and floor entirely with mirrors. Despite the reflections seeming infinite, he explains how they eventually drop off.
Recently seen in a much larger version, this intriguing piece of plastic distorts light in order to make objects placed behind it look like they’re invisible. NightHawkInLight goes beyond the wow factor to explain how the prisms in this fresnel lens work their magic. If you want to play with a Lubor’s lens, you can find a bunch on Amazon.
Canadian camouflage experts Hyperstealth Biotechnology has recently applied for patents on their technology which can bend light around an object to make it vanish from sight when placed in its sweet spot. The paper-thin screen could be used to hide military targets from ground-level threats. More on Vimeo.
Schlieren imaging is a method of visualization which plays with light refraction to capture images of normally invisible fluid patterns like air movement. Here, Veritasium walks us through a variant which uses colored filters to produce some astounding images.
