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 ...

Learn about the thermal light echo, observed by NASA, that causes intricate layers of interstellar gas and dust to emit an ...

A Japanese research team has "seen the light" and is utilizing infrared wavelengths to generate electricity, an untapped energy source that accounts for nearly half of solar energy striking the Earth.

The rig uses curved metal tracks to guide a pair of IR light sources through an arc centered on the focal point of the microscope stage. The angle of each light source relative to the stage can be ...

Since the invention of the laser in 1960, nonlinear optics has aimed to broaden light's spectral range and create new ...

Researchers developed a type of infrared photodiode that is 35% more responsive at 1.55 m, the key wavelength for telecommunications, compared to other germanium-based components.

Typically used with infra-red cameras, scopes, and night vision goggles for surveillance, these filters enable infrared energy to be emitted from a variety of light sources while blocking visible ...

The TB300-IR Laboratory Turbidimeter is designed for quick and easy turbidity measurement in the laboratory.Using an infrared (IR) light source and 900 detection, the TB300-IR conforms with ISO ...
