Introduction to Polarized Light | Nikon’s MicroscopyU

In linearly polarized light, the electric vector is vibrating in a plane that is perpendicular to the direction of propagation, as discussed above. Natural light sources, such as sunlight, and artificial sources, including incandescent and fluorescent light, all emit light with orientations of the electric vector that are random in space and time.

Nitride Semiconductors launches 365nm UV-LED chip for ...

May 28, 2020 · For accurate exposure, parallel light is required. However, UV-LED light sources generally have a wide directional angle (of about 120°), and the amount of light captured for exposure tends to be insufficient. Therefore, by combining a deep reflector with a lens of high UV transmittance, the firm has achieved a directional angle of 15° or less.

The trouble with UV light in your biosafety cabinet | EHS

Nov 08, 2018 · Penetration – In the dynamic air streams of BSCs, microorganisms beneath dust particles, plastics, and work surfaces are not affected by the UV light because it cannot penetrate particles so far from the UV source. Relative humidity – The germicidal effects of UV light drop off precipitously when relative humidity is above 70%.

Successful Light Polarization Techniques | Edmund Optics

Another example of polarization is the partial polarization of light reflecting from a plane surface, an effect less dramatic than a polarizer element. Linear polarization of a randomly polarized light source reduces the intensity of the source theoretically by 50%, and in practice closer to 60-65%.
