Raman scattering occurs when light interacts with molecular vibrations.

Fuchs et al. (1989) have observed effects from UVA and visible light on skin, whereas Cho et al. (2008) have looked at visible light and IR; however, only Mahmoud et al. (2010) have discussed the potential effects of visible light on skin. Hi, I'm trying to think up a way to shift IR rays into visible light spectrum so that the human eye can effectively see the IR image.

Infrared Light wavelengths and camera response is an importantant factor when choosing a CCTV camera or Webcam to use at night. The visible spectrum is

UV light is measured in microwatts of ultraviolet radiation per lumen of visible light (µW/l). Our eyes are sensitive to a narrow band of electromagnetic waves known as the visible light spectrum. To understand how visible light is broken into various wavelengths, take a cue from Isaac Newton and shine a light through a prism. The US military uses strobe marker lights that emit a strong visible strobe, but beneath a blackout shield so the light is only visible with night vision or other iR sensitive devices, and is 100% invisible to the naked eye.

Scientists use the various waves in the EM Spectrum to measure and study our universe. The US military uses strobe marker lights that emit a strong visible strobe, but beneath a blackout shield so the light is only visible with night vision or other iR sensitive devices, and is 100% invisible to the naked eye. A strong LED could also have such a coating if needed.

The main hazard to the eyes is that prolonged exposure The wavelength range is from about 1 millimeter down to 750 nm. The range adjacent to the visible spectrum is called the "near infrared" and the longer Infrared Light wavelengths and camera response is an importantant factor when choosing a CCTV camera or Webcam to use at night.

Infrared heat is a form of light sitting on the electromagnetic spectrum between microwaves and visible light. Since it heats and works almost similar to the sun.

Since visible light is a form of a wave, it is defined by its characteristic wavelength and frequency. The visible light spectrum is located within a wavelength range of 380 to 740 nanometers (nm) or frequency range of 405 to 790 terahertz (THz). IR and UV are each just beyond opposite ends of the visible spectrum. The visible spectrum sits between them. A UV-pass filter by definition cuts off everything longer. An IR-pass filter cuts off everything shorter. Visible light is generally defined as the portion of the electromagnetic spectrum between 380–400 nanometers (nm) and approximately 760 nm.
