Everyone is going nuts over this new reflex lens. Don't they know how horrible reflex lenses are?
The Kase Reflex 150mm f/5.6 AF is getting a lot of hype online –but does nobody remember how bad these lenses are?
Researchers have developed an extremely thin, flexible imager that could be useful for noninvasively acquiring images from inside the body. The new technology could one day enable early and precise ...
With the development of photonic chips and nano-optics, the old ground glass lenses can't keep up in the race toward miniaturization. In the search for a suitable replacement, a team from the ...
One of the oldest problems in optics has been solved. Rafael Gonzalez from Mexico's Tecnologico de Monterrey has come up with an almost comically dense equation that can be used to almost completely ...
California-based accessory maker Sandmarc has launched a new Tetraprism 72mm Lens for iPhone that adds 3x optical ...
Researchers are making progress toward a “perfect lens” that will be able to resolve an organelle assembling a protein or a virus attacking a cell. From ribosomes assembling proteins to viruses ...
Optical metasurfaces are two-dimensional arrays of nano-scatterers that modify optical wavefronts at subwavelength spatial resolution. They are poised to revolutionize optics by enabling complex ...
Aspheres allow designers to build smaller, lighter and simpler optical systems, and can be found in everyday products. Edwin Diaz provides a back-to-basics guide to the technology. You may not realize ...
