Optical spectroscopy is a fundamental tool in numerous areas of science and technology. Much effort has focused on miniaturizing spectrometers, but thus far at the cost of spectral resolution and ...

Figure 1. Mid-IR spectra of common polymers. Figure 2. Spectrum Two FT-IR with UATR. Further spectral interpretation can provide structural data, for instance, while observing the C–H stretch region ...

IR spectrum of the plant-based bag sample. Image Credit: Edinburgh Instruments. Figure 4 presents the IR spectra of the juice and soft drink bottles. Both samples were identified as PET (PIC1 and ...

Similar to the visible light spectrum, which ranges from violet (the shortest visible-light wavelength) to red (longest wavelength), infrared radiation has its own range of wavelengths.

The image shows the same galaxy as seen through different wavelengths of light. On the left, in image (a), you see the Whirlpool in the visible light spectrum, at 0.4 microns (shown in blue) and 0 ...

Hong et al. constructed an unprecedented bright, smooth, and flat 300-5000 nm ultraviolet-visible-infrared full-spectrum femtosecond white-light laser source by exploiting the efficient second ...
