The preferred term for the shorter wavelengths in the infrared region extending from about 0.7 µm (visible red) to about 3 µm. The longer wavelength end grades into the middle infrared. Sometimes called solar infrared, as it is only available for use during the daylight hours. Also known as the shortwave infrared (SWIR).
The region of the electromagnetic spectrum between 0.77 to 1.4 microns. Most of the infrared solar radiation falls into this region. This near infrared (or solar IR) region is transmitted, absorbed, and reflected in a similar manner to visible light by most glazing and nonmetallic building materials.
electromagnetic radiation ranging from 0.7 to ~3 microns in wavelength
The shortest wavelength infrared radiation, measuring approximately 1 to 3 microns. This is also referred to as Short Wave Infrared.
The area of the spectrum between 700 nm and 2500 nm (2.5 µm).
The preferred term for the shorter wavelengths in the infrared region extending from about 0.7 µm (visible red), to around 2 or 3 µm (varying with the author). The longer wavelength end grades into the middle infrared. The term really emphasises the radiation reflected from plant materials, which peaks around 0.85 µm. It is also called solar infrared, as it is only available for use during the daylight hours.
The part of the infrared electromagnetic spectrum near visible wavelengths, in the range of 700 to 1500/2000 nm.
Infrared radiation having wavelengths extending from approximately 0.7 to 1.3 micrometers.
The shortest wavelength infrared radiation band - 0.7 to 1.4 microns.
The part of the infrared near the visible spectrum, typically 700 nm to 1500 nm or 2000 nm; it is not rigidly defined.
