Paper-thin optical lenses simple enough to mass produce like microchips could enable a new generation of compact optical devices. Researchers have fabricated and tested flat lenses called Fresnel ...

However, their simple planar geometry prevents the creation of concave surfaces, limiting their ability to fully display intricate structures in a single view. To overcome these limitations, the ...

The OpenFlexture Microscope is a DIY, open-source, 3D-printed microscope built around the Raspberry Pi 4, a Raspberry Pi Camera Module v2, and a choice of optics or various qualities up to lab-grade ...

combination of thin lenses in contact, refraction of light through a prism, microscope and astronomical telescope (reflecting and refracting ) and their magnifying powers. Wave optics: wavefront ...

While much cheaper than standard equipment, there was a caveat: a microscope’s specially crafted glass lenses often cost hundreds of dollars, putting the tools out of many people’s price range.

Valerion’s VisionMaster Max can be upgraded with alternate lenses so you can install it closer or farther from a screen without sacrificing resolution. Valerion’s VisionMaster Max can be ...

She and her colleagues previously worked out how to 3D-print lenses like those used in microscopes, which led to the breakthrough. Receive a weekly dose of discovery in your inbox! We'll also keep ...
