Polarizing film is a layer often added to optical filters with anti-reflection coatings, as well as a range of other direct applications in optics, film and photography, and automotive. When light passes through the filter, the polarizing film only allows the transmission of light waves with a specific polarization, while blocking unwanted polarizations. The result […]
Diffraction gratings separate incident light into different wavelengths by passing it through a narrow slit, which causes the light wave to ‘bend’ and disperse. The principle is similar to refraction, but instead of being caused by the wave passing through a material of different density, it occurs whenever a beam of light passes close by […]
