Now it is difficult to imagine modern technologies and devices without using optical fibers that became an integral part of our life. The fiber applications include reaction monitoring, biomedicine, and biotechnology, IR-Fiber pyrometry, laser technology, spectroscopy, IR radiation delivery, thermosensing, IR-imaging, etc. Moreover, optical fiber systems are widely used in the aerospace sphere. It should...

Modern medicine does not stand still; it uses numerous technologies and devices. Nowadays it is possible to manage diseases that have been impossible to cure before. Also the process of surgery is safer now because scientists are able to examine every part of human body except the one – human brain. Brain remains the main...

Recently researchers from the USA have created a totally new type of air-filled optical fiber bundle that could highly change medical endoscopes that are used for minimally invasive surgeries or bronchoscopies. Moreover, the advanced fiber bundle creates new wavelengths for endoscopy that will be useful for diagnostics. These infrared wavelengths are able to produce images...

At the present time Fourier transform IR (FTIR) spectroscopy plays an important role in the medical area, because it allows examining biological samples with the aim of neurological and other diseases studying. FTIR spectroscopy is a universal technique for more extensive biological system research because of the interaction of molecules in the universe with IR...

It is undoubted that at the present time the most widespread used device in modern spectroscopy is fiber probes. It turns out that their flexibility and user-friendliness made fiber optic probes the perfect solution for monitoring real-time kinetic reactions, analyzing different samples, sampling in-vivo difficult. Initially, the most common fiber probe types included reflectance probes...

Nowadays the gem market is increasingly employing photonics technologies to meet the demands of the fine jewelry and gem industry. This is due to the fact that the technology used to produce synthetic gemstones makes it difficult for the gem market to identify treatments applied to stones. Also, it’s difficult to identify and classify natural...

Nowadays development of infrared fibers and hollow waveguides is in good progress to meet growing market demands for laser power delivery, flexible IR-imaging, and remote process-spectroscopy in the range from 1 to 18 μm. Silica fibers possess high transmission in a broad range from 180 nm to 2.2 μm. They can be used for spectroscopy...

Portable Raman Spectroscopy is a very useful tool for studying archeological sites, enabling in situ analysis and thus reducing the impact of these kinds on key cultural sites. With a reduction in the size of the Raman spectrometer, there has been an increase in the usage of Raman spectroscopy for archeological investigations. The portability enables...

Fiber probes have become one of the most widespread tools in modern spectroscopy thanks to their flexibility and user-friendliness. Fiber optic probes are the ideal solution for monitoring real-time kinetic reactions, analyzing large or awkwardly shaped samples, sampling in vivo difficult. There are four types of the most common fiber optic probes: Reflectance probes These...

Nowadays Raman spectroscopy has become a cost-efficient and much-appreciated tool with applications in material science and in-line process control for pharmaceutical, food & beverage, chemical and agricultural industries. For instance, Raman probes and based on them Raman systems are used across the whole value chain in the pharmaceutical industry. High-resolution Raman microscopes help researchers in...
