WebCoherence In wave optics, we make a distinction between coherent and incoherent sources of light. Any real source of light is not exactly monochromatic (single color), but has a range or band of frequencies, Δ f. An incoherent source of light lacks a specific direction and has a relatively large Δ f. By contrast, a coherent source has a specific direction with a much … WebJul 1, 2013 · ICNIRP Guidelines on Limits of Exposure to Incoherent Visible and Infrared Radiation ICNIRP Guidelines on Limits of Exposure to Incoherent Visible and Infrared Radiation Author International Commission on Non-Ionizing Radiation Protection (ICNIRP) Collaborators International Commission on Non-Ionizing Radiation Protection (ICNIRP) : sharing ownership of a microsoft form
