The basic principle of operation for time-resolved electron microscopy systems involves the irradiation of a sample with short electron pulses which capture rapid snapshots at specific intervals, determined by the length of these electron beam pulses. Most time-resolved electron microscopy electron beams feature pulses approaching the femtosecond regime, providing detailed insights into sample composition, dynamics, and structure with both high spatial and temporal resolution.
Laser Quantum (Novanta) specializes in femtosecond and picosecond laser technology with ultra-short pulses, high repetition rates, and application-based systems that offer unique capabilities and benefits to a wide variety of applications, including time-resolved electron microscopy.

CNI Optoelectronics Tech offers a Distributed Feedback (DFB)/Distributed Bragg Reflector (DBR)/Vertical-Cavity Surface-Emitting Laser (VCSEL). This laser is specially designed to detect gases, such as methane (CH4), hydrogen sulfide (H2S), ammonia (NH3), water (H2O), carbon monoxide (CO), carbon dioxide (CO2), ethane (C2H4), hydrogen fluoride (HF), acetylene (C2H2), and others.
Features of this laser include:
Ultrafast lasers produce extremely short pulses of light; usually on the order of pico- or femtoseconds. Relying on techniques such as mode locking to create a train of pulses, ultrafast lasers owe their recent success to relatively new developments in photonics. These advancements in laser technology enable the production of pulses ranging between a few femtoseconds to tens of attoseconds.
These ultrafast pulses foster the direct investigation and manipulation of atoms and electrons, thus extending the frontiers of science and technology to territories that were previously inaccessible.

Hyperspectral imaging is a powerful tool, enabling differentiation of multiple targets in highly dynamic environments. In some cases, it is the only solution. However, many machine vision applications can be addressed with multispectral techniques that are generally less expensive than more complex hyperspectral systems.
On Wednesday, July 20, join Principle Product Engineer John Atkinson of Chroma Technology Corp. in a discussion about optical filter technology in the SWIR wavelength range, practical applications for multispectral techniques, and appropriate filter specification.

For multi-kW lasers used in welding, it is often difficult to sample both main beam power and get a beam profile at the same time, as cameras often have much higher sensitivity (and lower LDT) compared to power meters for high power ranges. This issue can be solved by using a single, diffractive sampler.
A diffractive laser beam sampler is a Diffractive Optical Element (DOE) designed to split a sub-beam identical to the main beam, with a pre-determined small fraction of power, for example 0.2%. The main beam power can be sampled directly from the sample forward order with a power meter. While the reflected, sampled order (which is attenuated by another factor of ~100 compared to the forward order) can be used with a camera to monitor the beam profile. This enables real-time control of both power stability and beam profile.

Chroma Technology announced today that its ContrastMax SWIR optical filters for machine vision and remote sensing were recognized among the best in machine vision today by the judges of the Vision Systems Design 2022 Innovators Awards program at the Automate Show in Detroit, MI. The judging panel consisted of esteemed experts from system integrators and end-user companies.
In a recently published article, entitled “High-resolution snapshot hyperspectral computed tomography imaging spectrometer (CTIS): real-world applications,” a custom diffractive optical element (DOE) produced by Holo/Or was used for experimental confirmation of a novel optical imaging system.
This application is to distinguish between real apples and fake plastic apples. These two types of object are “visually indistinguishable to the naked eye.” The results show that the system can discern the fake apples based on the reconstructed spectral signature. “This work shows the capabilities and potential of CTIS in real-world applications and paves the way for future real-time snapshot hyperspectral imaging.”

The Mar Hospital located in Barcelona, Spain, has inaugurated a new intensive care unit (ICU) facility, built in just five months and with capacity for eighteen new beds. The new facility includes a circadian lighting system based on LEDMOTIVE light expertise and products. The hospital has installed downlight and spotlights with LEDMOTIVE’s award-winning VEGA07 multispectral technology.
The control system, implemented by LEDMOTIVE, integrates the luminaires. The health personnel can operate the LIGHT HUB with KNX smart switches to dimerize the box or switch to medical examination mode, which maximizes illuminance level and color precision.
