Here is an economical way to experiment with light, color, and optics. You get one Red LED light source, one Green LED light source, and one Blue LED light source. The three LEDs can be controlled ...

[Peter] has finished up his fiber optic microscope light source. When we last visited [Peter] he created a dimmer circuit for a 10 watt LED. That LED driver has now found its final home in [Peter’s] ...

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 ...

News-Medical speaks to Robert Schmalzigaug from Evident, to explore the field of bioluminescence imaging and the applications of the LV200 microscope. Bioluminescence is a natural phenomenon in which ...

Receive emails about upcoming NOVA programs and related content, as well as featured reporting about current events through a science lens. The new microscope uses a 405 nm laser—the same wavelength ...

For the majority of fluorescence microscopy experiments, controlling all components through software is the most efficient way to achieve optimum settings – and optimum results. Many modern LED ...

Researchers have demonstrated a way to increase the resolution of microscopes and telescopes beyond long-accepted limitations by tapping into previously neglected properties of light. The method ...

"Our dream was to invent a window into the brain, so we could see what happens inside when we’re thinking, planning, feeling, and remembering,” says Professor May-Britt Moser, describing conversations ...
