2. Far infrared - Wikipedia

   en.wikipedia.org/wiki/Far_infrared

   Far infrared (FIR) or long wave refers to a specific range within the infrared spectrum of electromagnetic radiation. It encompasses radiation with wavelengths ranging from 15 μm (micrometers) to 1 mm, which corresponds to a frequency range of approximately 20 THz to 300 GHz. This places far infrared radiation within the CIE IR-B and IR-C ...

3. Infrared - Wikipedia

   en.wikipedia.org/wiki/Infrared

   In infrared photography, infrared filters are used to capture the near-infrared spectrum. Digital cameras often use infrared blockers. Cheaper digital cameras and camera phones have less effective filters and can view intense near-infrared, appearing as a bright purple-white color. This is especially pronounced when taking pictures of subjects ...

4. Near-infrared window in biological tissue - Wikipedia

   en.wikipedia.org/wiki/Near-infrared_window_in...

   The near-infrared (NIR) window (also known as optical window or therapeutic window) defines the range of wavelengths from 650 to 1350 nanometre (nm) where light has its maximum depth of penetration in tissue. [1] Within the NIR window, scattering is the most dominant light-tissue interaction, and therefore the propagating light becomes diffused ...

5. Electromagnetic spectrum - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_spectrum

   The infrared part of the electromagnetic spectrum covers the range from roughly 300 GHz to 400 THz (1 mm – 750 nm). It can be divided into three parts: [1] Far-infrared, from 300 GHz to 30 THz (1 mm – 10 μm). The lower part of this range may also be called microwaves or terahertz waves.

8. Photothermal therapy - Wikipedia

   en.wikipedia.org/wiki/Photothermal_Therapy

   Photothermal therapy (PTT) refers to efforts to use electromagnetic radiation (most often in infrared wavelengths) for the treatment of various medical conditions, including cancer. This neurotherapy is an extension of photodynamic therapy , in which a photosensitizer is excited with specific band light.

9. Non-ionizing radiation - Wikipedia

   en.wikipedia.org/wiki/Non-ionizing_radiation

   Near ultraviolet, visible light, infrared, microwave, radio waves, and low-frequency radio frequency (very low frequency, extremely low frequency) are all examples of non-ionizing radiation. By contrast, far ultraviolet light, X-rays, gamma-rays, and all particle radiation from radioactive decay are ionizing.
