Infrared - Wikipedia
网页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.
The Correct Material for Infrared (IR) Applications - Edmund …
网页As the need for IR applications grows and technology advances, manufacturers have begun to utilize IR materials in the design of plano-optics (i.e. windows, mirrors, polarizers, beamsplitters, prisms), spherical lenses (i.e. plano-concave/convex, double-concave/convex, meniscus), aspheric lenses (parabolic, hyperbolic, hybrid), achromatic ...
Infrared Waves - Science@NASA
网页2016年8月10日 · Infrared waves, or infrared light, are part of the electromagnetic spectrum. People encounter Infrared waves every day; the human eye cannot see it, but humans can detect it as heat. A remote control uses light waves just beyond the visible spectrum of light—infrared light waves—to change channels on your TV.
What is Infrared? Lets Look at Infrared Light & Beam and How …
网页2024年9月12日 · Infrared light or infrared radiation (IR) is a kind of radiant energy that is invisible to the human eye however, people can feel it as heat. Every object in the universe can emit IR radiation at some level and the most well-known sources are fire and the sun.

网页2023年3月16日 · The beam of infrared radiation passed through the air, indicating that the major constituents of air (nitrogen gas, N 2, and oxygen as, O 2) either do not absorb infrared radiation or absorb in another region of the spectrum. You likely know that double and triple bonds have strong absorptions in the mid-IR region of the spectrum.
4.2: IR Spectroscopy - Chemistry LibreTexts
网页Infrared spectroscopy is based on molecular vibrations caused by the oscillation of molecular dipoles. Bonds have characteristic vibrations depending on the atoms in the bond, the number of bonds and the orientation of those bonds with respect to …
Infrared Light - an overview | ScienceDirect Topics
网页Infrared light is an electromagnetic radiation between microwave and visible light, with a wavelength of 0.78 ∼ 1000 μm, including near-infrared (NIR, 0.78 ∼ 1.4 μm), short-wavelength infrared (SWIR, 1.4 ∼ 3.0 μm), mid-wavelength infrared (MWIR, 3.0 ∼ 8.0 μm), and long-wavelength infrared (LWIR, 8.0 ∼ 15.0 μm) [1,2].
