This time it is a writeup on the best ways to create IR light sources from regular lights. Since normal flashlight bulbs emit a broad enough spectrum to include visible light and IR light ...

Since the invention of the laser in 1960, nonlinear optics has aimed to broaden light's spectral range and create new frequency components. Among the various techniques, supercontinuum (SC) generation ...

The standard design is simple; a prism or diffraction grating to break up a light source into a spectrum and a detector to measure light intensity. Shine the light through your sample, scan ...

are also light sources. They make their own light to attract mates to breed with. We can split white light into a spectrum of colours using glass prisms or the reflective side of a CD. Most ...

But the output spectrum, like that of fluorescent tubes ... Through testing to the standards, LEDs, luminaires and other light sources are divided into four groups: exempt (completely safe), and risk ...

Researchers at Tel Aviv University developed a groundbreaking method to synthesize spatial coherence during nonlinear optical ...

But did you know that there's more to light than meets the eye? Let’s explore the amazing world of the electromagnetic spectrum! The electromagnetic spectrum has many types of light waves. It includes ...

About 50km (30 miles) north of Beijing’s city centre, construction is wrapping up on what is expected to be the world’s brightest X-ray light source, slated to switch on later this year to ...
