Researchers have incorporated a swept illumination source into an open-top light-sheet microscope to enable improved optical sectioning over a larger area of view. The advance makes the technique more ...

This relatively simple circuit uses a 6-V DC supply with a PWM current-source configuration to provide efficient, adjustable dimming of a white LED over a wide range, needed to accommodate the unique ...

Light microscopy does much what the name implies: visible light and magnifying lenses are used to view small objects. Light microscopes are the oldest form of higher quality imaging devices, dating ...

Researchers have created the world’s smallest silicon LED and holographic microscope that opens up a wide range of potential applications, including turning your smartphone camera into a portable, ...

Powerful microscopes have made a quantum leap. Using a quantum trick with light has allowed researchers to examine living cells in unprecedented detail without destroying them, a technique that could ...
