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 ...

With the launch of the Leica DM2500 LED, Leica Microsystems completes its Leica DM1000 to 3000 series of microscopes. All the models in this series are now available with LED illumination. The Leica ...

Leica Microsystems has launched two instruments of the laser microdissection microscope series, the Leica LMD6 and the LMD7, with LED illumination for transmitted light. Users can now choose between ...

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 ...

[Amen] obtained a microscope whose light source was an incandescent bulb, but the light from it seemed awfully dim even at its brightest setting. Rather than hunt down a replacement, he decided to ...

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, ...

This is the world’s smallest silicon (Si) light-emitting diode (LED) - smaller than the wavelength of light - with a light intensity comparable to much larger, state-of-the-art Si LEDs and with ...
