It’s relatively easy to understand how optical microscopes work at low magnifications: one lens magnifies an image, the next magnifies the already-magnified image, and so on until it reaches the eye ...

The Micro Phone Lens can turn any smartphone or tablet computer into a hand-held microscope. The soft, pliable lens sticks to a device's camera without any adhesive or glue and makes it possible to ...

A lens-free microscope that can be used to detect the presence of cancer or other cell-level abnormalities with the same accuracy as larger and more expensive optical microscopes, has been developed ...

The little picture: Microscopes are cool. There is something fascinating about looking at objects that you cannot normally see with your naked eye. Of course, carrying a microscope around for whenever ...

Figure 1: Partially coherent lens-free on-chip microscope. In addition to temporal-coherence requirements, spatial coherence of the illumination is also critical in lens-free holographic microscopy ...
