Infrared light is invisible to the human eye, but heat sensors can detect longer infrared waves. Infrared shares some characteristics with visible light, however. Like visible light, infrared light can be focused, reflected and polarized. Wavelength and frequency Infrared is typically subdivided into ...
Infrared radiation is light that is just beyond what is visible to the human eye. Although we cannot see IR light, we can feel it as heat. In IR microscopy, a material of interest absorbs radiation from a range of wavelengths in the IR spectrum. Scientists measure and analyze the IR abso...
摘要: A mapping method for producing an infra-red map utilizing IR coatings on substrates such as microscope slides. The invisible map can be used for positioning a microscope platform or for locating microscopic objects without interference from visible or ultraviolet light....
Infrared is an energy similar to visible light, but with a longer wavelength. Infrared energy is invisible to the human eye, however, while visible light energy is emitted by objects only at a very high temperature, infrared energy is emitted by all objects at ordinary temperatures....

This device is equipped with 60 high-powered LEDs, but only 30 of them will appear visible as red lights. That's because the remaining 30 LED microchips are emitting light in the near-infrared spectrum, which is invisible to the human eye....
Figure 2 shows log( - ln(transmittance), for the set of data presented in Fig. 1. Excluded from the analysis were data with transmittances (after division by maximal transmittance) between 1.000 and 0.990 or 0.010 and 0.000, because they are relatively inaccurate after the log( - ln) ...
Infrared light is not visible to the human eye but is felt in the form of heat. Controlling light at this wavelength is desirable for a wide range of applications like developing camouflage platforms that might be useful in military operations. ...
