2. Infrared lamp - Wikipedia

   en.wikipedia.org/wiki/Infrared_lamp

   Infrared lamps are also used for some night vision devices where visible light would be objectionable. Infrared lamp sources are used in certain scientific and industrial instrument for chemical analysis of liquids and gases; for example, the pollutant sulfur dioxide in air can be measured using its infrared absorption characteristics. IR ...

   An HMI head on a stand. Hydrargyrum medium-arc iodide (HMI) is the trademark name of Osram's brand of metal-halide gas discharge medium arc-length lamp, [1] made specifically for film and entertainment applications. Hydrargyrum comes from the Greek name for the element mercury. An 18kW HMI Bulb

4. Infrared - Wikipedia

   en.wikipedia.org/wiki/Infrared

   Infrared (IR; sometimes called infrared light) is electromagnetic radiation (EMR) with wavelengths longer than that of visible light but shorter than microwaves. The infrared spectral band begins with waves that are just longer than those of red light (the longest waves in the visible spectrum ), so IR is invisible to the human eye.

5. Infrared spectroscopy - Wikipedia

   en.wikipedia.org/wiki/Infrared_spectroscopy

   The method or technique of infrared spectroscopy is conducted with an instrument called an infrared spectrometer (or spectrophotometer) which produces an infrared spectrum. An IR spectrum can be visualized in a graph of infrared light absorbance (or transmittance ) on the vertical axis vs. frequency , wavenumber or wavelength on the horizontal ...

   The Advanced Target Pointer Illuminator Aiming Laser, ATPIAL AN/PEQ-15 known colloquially as the "PEQ-15" [/ p ɛ k / / f ɪ f t iː n /] produced by L3Harris (originally designed and manufactured by Insight Technology, until their acquisition by L3Harris in 2010); is a multifunction IR Target Pointer & Illuminator, a.k.a. a Laser Aiming Module (LAM) for use as a rifle attachment, using a ...

7. AN/PEQ-2 - Wikipedia

   en.wikipedia.org/wiki/AN/PEQ-2

   The AN/PEQ-2 has two infrared laser emitters;one narrow beam used for aiming the rifle and one wide beam used for illuminating targets, like a flashlight. [9] The beams can only be seen through night vision goggles. [9] Each beam can be zeroed independently, and the illuminator's radius is adjustable. The two lasers are tied into one 6-mode ...
