The Dawn of New Optics: Emerging Metamaterials
Science has long sought novel or modified materials that could reach beyond the conventional laws of optics to replace bulky glass and polymer optical components with flatter, more robust, lower-cost, stackable ones — perhaps even with subwavelength properties that could benefit virtually every light-enabled device from cellphones to microscopes. One goal of a tunable, isotropic negative-index (left-handed) metamaterial is control of both phase and amplitude of light, an advancement that could lead to optical cloaking, holographic displays, and quantum levitation.

Technological Synergies Move Spectroscopy Out of the Lab
Spurred by manufacturing advancements over the past decade, lasers, sensors, and imaging devices have become more compact and reliable. This progress has allowed spectroscopy to grow into new and diverse fields. The tabletop semiconductor laser, the benchtop FTIR (Fourier transform infrared) and hand-held x-ray fluorescence (XRF) spectrometers, and the advent of silicon photonics are opening new areas of inquiry and industry — often for individuals untrained in spectroscopy.

Trends in Industrial Laser Solutions
The demands on lasers grow as the need for precision in manufacturing and other applications increases. In general, lasers enable processes that cannot be performed economically in any other way — such as drilling holes, selectively removing material, or texturing a surface. Lasers also allow novel methods of imaging. Such uses may require a variety of laser advancements, however, including shorter pulse width, higher repetition rate, varying wavelengths, greater power, better beam quality, and improved uptime.

Filters for Hyperspectral Imaging
Delta Optical Thin Film A/S
Hyperspectral imaging has been used for a couple of decades in applications such as satellite imaging, air reconnaissance and other not overly price sensitive markets. Classical Hyperspectral imaging cameras use prisms or grating as dispersive elements. These cameras are bulky, sensitive to misalignment and very expensive.

SiPM and SPAD: Emerging Applications for Single-Photon Detection
Thu, Jan 17, 2019 2:00 PM - 3:00 PM EST
This webinar, presented by Hamamatsu Corporation, will provide a thorough overview of silicon photomultipliers (SiPMs) and single-photon avalanche photodiodes (SPADs) for low-light level photodetection. Compared to photomultiplier tubes (PMTs), SiPMs and SPADs are smaller, more durable, and more energy efficient. They also offer better immunity to magnetic fields and ambient light than PMTs. By attending this webinar, you will gain a better understanding of SiPM and SPAD technology, so you can determine whether it is the right choice for you.
