Quantum technology is seen as an important future-oriented technology: smaller, faster and with higher performance than conventional electronics. However, exploiting quantum effects is difficult because nature’s smallest building blocks have properties quite distinct from those we know from our everyday world.
From checkout counters at supermarkets to light shows at concerts, lasers are everywhere, and they’re a much more efficient light source than incandescent bulbs. But they’re not cheap to produce.

Flexible endoscopes are used in medical procedures where the scope cannot bend. This animation from SCHOTT demonstrates the transmission of light and data through external and internal rigid fiber optic light cables in endoscopy.
One of the key parameters for understanding how a laser will perform in an application is the spatial intensity distribution. In many industial laser cutting or welding applications, monitoring the beam quality is critical for successful operation. The measurement of the beam can either be made during the design stage of the laser, or it might be more sufficient for continuous real-time monitoring during the laser’s operation. This white paper addresses the general need for laser beam profile analysis, describes laser beam analysis instruments, and provides an overview of laser applications, in particular for infrared wavelengths.

Turbulent flows laced with particles can be found everywhere, including fuel droplets in combustion engines, to airborne pollen, to water droplets in clouds. Even though they have been studied often, questions still remain that have to do with the particles’ inertia prohibiting them from following turbulence flow, making the Navier-Stokes equations insufficient for solving their equations. This white paper presents a project studying the dynamics of inertial droplets in a turbulent flow in a well-controlled environment. Measurements of droplet size distribution and turbulent dispersion rate in this study are done with interferometric particle imaging (IPI) and phosphorescent tagging techniques.
The introduction of 3-D machine vision systems to automation processing overcomes the technological hurdles of machines being able to “see,” analyze, and make decisions in an unpredictable environment. Designed specifically for factory work, these new machines meet production requirements of high accuracy, speed, and low maintenance while also being durable enough to withstand factory conditions.
When designing micromaterial processing equipment, manufacturers need to consider a complex interplay of numerous factors, such as extremely accurate positioning of lasers for cutting, drilling, scribing, or for marking at the highest rate possible. For many integrated circuits, the required beam accuracies can be staggering. For example, processing equipment must be able to drill microvias and scribe trenches less than 10 μm in size. Display manufacturers must also accurately place and repair pixel circuitry at ever shrinking resolutions on increasing larger substrates. This requires advance tooling to avoid significant increases in processing time and costs.
As hexapod motion and positioning platform become more mainstream technologies, their applications have expanded into medical fields such as dental biomechanics. The growth into these new dental applications and research requires a solution for the challenges in dealing with the combinations of small forces with large deflections, as well as large forces and extremely small deflections. In order to deal with this challenge, the HexMeS (Hexapod Measuring System) was designed. This article details the use of the HexMeS and highlights the key reasons for choosing hexapod motion systems in dental research applications.
