Photonic Crystal Generates VUV Light at Wavelengths Suitable for Spectroscopy
Photonic Crystal Generates VUV Light at Wavelengths Suitable for Spectroscopy
Researchers at the University of Tokyo have created a tabletop device that efficiently generates circularly polarized vacuum ultraviolet (VUV) light using an ultrathin film with nanoscale perforations. VUV wavelengths, which can be absorbed by air but can pass through a vacuum, are useful for chemical and physical analyses, especially VUV wavelengths in the region of around 120 to 200 nm.

Avantes BV - New: The AvaSpec-Mini-NIR Spectrometer New: The AvaSpec-Mini-NIR Spectrometer

Avantes BV
The latest addition to our compact line: the AvaSpec-Mini-NIR! This compact, versatile near-infrared spectrometer is suitable for many different applications, including but not limited to food analysis and recycling. Though not as sensitive as our bigger NIR spectrometers, the loss in sensitivity is greatly compensated by its size and robustness, which makes this spectrometer extremely suitable for handheld applications.

Introduction to Photodetectors - Hamamatsu Corporation
Photodetectors—such as photodiodes (PDs), avalanche photodiodes (APDs), photomultiplier tubes (PMTs), and silicon photomultipliers (SiPMs)—are essential components in a vast array of modern scientific and commercial instruments and devices; technological progress will make them even more ubiquitous. Part 2 of this two-part webinar discusses the following topics: photodetectors’ structures and operation, their applications, and the selection of a photodetector.

Room-Temperature Terahertz Quantum Cascade Lasers
Room-Temperature Terahertz Quantum Cascade Lasers
The terahertz (THz) spectral range between the infrared and microwave has long been recognized as an unexploited range of frequency bands. It has considerable potential for application in numerous fields, including communications, imaging, spectroscopy, and biological engineering since the THz wave can pass through nonconducting materials such as many dielectric materials, semiconductors, and medicines.
