Researchers have developed a liquid crystal lens that blocks triggering wavelengths of light without ruining the moviegoing ...

He’s still improving the Motobrain, and he wanted to better understand the thermal characteristics of the high current draws (upwards of 100amps!) After you’ve checked out [Josh’s] blog for ...

[David Prutchi] writes in to tell us about his recent experiments with building lenses for thermal imaging cameras, which to his knowledge is a first (at least as far as DIY hardware is concerned).

Meanwhile, the University of Michigan is working on a lens that contains thermal imaging technology, essentially giving the wearer night vision. The implications are staggering. That functionality ...

As a writer and photographer, I think a lot about perception: how it is limited by the ways our senses have evolved, how ...

And note the emphasis on the word ‘systems' of which the basic thermal camera is just a part. One of the biggest cost drivers of a long-range uncooled system is the lens. As effective range ...

The thermal lens leads the industry in optical clarity and provides a distortion and fog free field of vision regardless of the weather. The anatomically correct i4 mask system offers the best in ...

He added “Developing an athermalized lens design, is especially critical in the infrared (8 – 14 micron) waveband because the coefficient of thermal expansion of most infrared materials is ...
