Researchers have incorporated an innovative ultra-broadband, quantum-entangled light source that generates a relatively wide range of infrared photons with wavelengths between 2 m and 5 m for ...

Near-IR spectroscopy belongs to the group of vibrational spectroscopy techniques, along with mid-infrared spectroscopy (primarily FT-IR) and Raman spectroscopy. The first near-IR spectrometers were ...

Near-infrared spectroscopy, known as NIR spectroscopy or NIRS, is a long-established analytical technique. For over 30 years, it has proven to be a fast and reliable method for measuring chemical and ...

Definition: Fourier Transform Infrared (FTIR) Spectroscopy is a highly specialized type of IR spectroscopy. It's the most common way IR measurements are carried out today. FTIR is known for its speed, ...

The human eye can only see a small part of the much broader spectrum of electromagnetic radiation (Figure 1). On the high-energy side of the visible spectrum lies the ultraviolet (UV) region, while on ...
