WebThe Importance of Using the Correct Material. Since infrared light is comprised of longer wavelengths than visible light, the two regions behave differently when propagating through the same optical medium. Some materials can be used for either IR or visible applications, most notably fused silica, BK7 and sapphire; however, the performance of ... Webin the absorption spectrum and frequently the emission spectrum will be approximate to a mirror image of the absorption spectrum. Since the emission of fluorescence always takes place from the lowest vibrational level of the first excited state, the shape of the emission spectrum is always the same, despite changing the wavelength of exciting ...

WebHyperspectral and multispectral imaging are used in agriculture to monitor the health of fields across a broad range of the electromagnetic spectrum. In typical machine vision applications, the illumination used and captured by the sensor is from roughly 400 nm (violet) to 700 nm (dark red) (Figure 1). The light is often collected with imaging ...
WebNEAR INFRARED RADIATION A portion of radiation that is just beyond the visible spectrum is referred to as near-infrared.

Typically, it is taken to extend from the nominal red edge of the visible spectrum at 700 nanometers (nm) to 1 millimeter (mm). This range of wavelengths corresponds to a frequency range of approximately 430 THz down to 300 GHz. Beyond infrared is the microwave portion of the electromagnetic spectrum.
