Injection molding seemed easy—until I tried machining a double convex lens mold. From surface finish to mold alignment, this “simple” project got real fast.

The finished module is integrated into the instrument as follows: plug the fixed kinematic mount base into the instrument; the floating kinematic lens unit is then mounted into the fixed kinematic ...

By carefully placing nanostructures on a flat surface, researchers at Linköping University, Sweden, have significantly ...

By carefully placing nanostructures on a flat surface, researchers have significantly improved the performance of so-called optical metasurfaces in conductive plastics. This is a major step for ...

Linköping University researchers achieve a tenfold performance boost in conductive polymer metasurfaces, advancing the field ...

Make a lens and a magnifying glass by filling a bowl with water. A round bowl of water can act as both a magnifier and a lens. Place the lightbulb or candle more than 1 foot (30 cm) from the ...

I tend to find that the best lenses for landscape photography are wide-angle zooms. Zoom versatility is great for fine-tuning your composition without forcing you to try to get to inaccessible vantage ...

The best cheap lenses prove that you don't have to spend mega-bucks in order to create fantastic images. After all, not everyone has a huge budget to spend on their photography, and manufacturers know ...

Interchangeable lens cameras, or cameras that let you swap out lenses, can unlock a lot of opportunities and new creative control for your photography. That's because different focal lengths (offering ...

Monofocal and multifocal lenses are both types of artificial intraocular lens (IOL). A monofocal lens has one focusing distance, whereas a multifocal lens can focus on close and far distances at ...
