Spectrometers — devices that distinguish different wavelengths of light and are used to determine the chemical composition of everything from laboratory materials to distant stars — are large devices with six-figure price tags, and tend to be found in large university and industry labs or observatories.
Many semiconductor fabricators and research labs are under increasing pressure from, of all things, vacuum. These facilities need to remove greater amounts of gas molecules and particles from their setups as new technologies and processes demand lower and lower pressures.
Diamond nanomaterials are considered hot candidates for low-cost photocatalysts. They can be activated by light and can then accelerate certain reactions between water and CO2 and produce carbon-neutral "solar fuels".
According to the EU’s Waste Electrical and Electronic Equipment (WEEE) Directive, 85 % of PV waste must be recovered and 80 % recycled and reused, by 2018.

Automotive journalist, Alex Roy, talks about thermal cameras in autonomous driving with Stuart Klapper from Veoneer and Paul Clayton from FLIR Systems.
Measuring very low power beams of light can be tricky; even small values of noise, drift or offset can have major impact on your readings. In this video, we’ll look at some best practices that can help you get the best performance from your very low power measurements.
Scanning slit profilers can make very accurate measurements of beam diameters as small as 5 microns, while cameras are limited to beams greater than 45 microns. This makes applications for focusing lasers or building optical systems much easier with a NanoScan. This video explains how to choose the right NanoScan for your application.
This video introduces First Sensor’s core competencies available from design concept to production.

Used in the operating room for decades, optical fibers continue to enable new devices for minimally invasive surgeries and light-based disease detection that are enhancing the application of optics in modern medicine.
Pyroelectric detectors are thermal detectors that use temperature fluctuations to create a charge change on the surface of pyroelectric crystals, which produces a corresponding electrical signal. This application note discusses the materials used for their fabrication, how they operate, and their ideal applications.
“What’s a ‘steering wheel’?” At the present time this would be a very strange question to hear asked from anyone who has driven, ridden in, or even seen a car but in a couple of decades this may not seem so unusual. The evolution of increasingly affordable and capable sensing and imaging systems combined with the desire to create safer, more efficient transportation systems is driving the development of autonomous vehicles (pun intended). LiDAR is a key technology that will eventually help carry this growth through to “Level 5” autonomy --> no steering wheels, no brake pedals, no human intervention in driving.
Phosphor-coated CCD cameras have their place in gross beam alignment and applications where essential beam diagnostics are not required. However, due to the wide wavelength range of InGaAs cameras, the very high sensitivity of the array with very low noise, the real characteristics of the 1.5mμm beam can be detected, imaged, and measured with true accuracy. This white paper describes how the phosphor camera is the wrong solution for accurate beam diagnostic measurements and discusses how InGaAs cameras excel in this area.
The question how certain algal enzymes accomplish the high proton transfer rate for hydrogen production had in the past been subject to speculation. Dr. Martin Winkler, Dr. Jifu Duan, Professor Eckhard Hofmann and Professor Thomas Happe from Ruhr-Universität Bochum (RUB), together with colleagues from Freie Universität Berlin, traced the pathway of protons all the way into the active center of [FeFe]-hydrogenases.
