Figure 1: Splash is suppressed when the ambient air pressure is reduced. A drop 3.4mm in diameter of ethanol colliding with a surface at a speed of 3.74 ms-2 splashes at atmospheric pressure (top panel) but spreads smoothly at 0.172 atmospheres (bottom panel).

Quantum Composersmodel 9528 Digital Delay Pulse Generators has been incorporated for use as a timing system at Brown University, of Providence, RI, in a research project which has begun to reveal the hidden mysteries of how liquid droplets splash.
The mechanism behind liquid droplet splashing on a smooth dry surface is not completely understood. It was recently discovered that reducing ambient pressure can suppress splashing altogether. Shreyas Mandre, Assistant Professor, School of Engineering, Brown University and colleagues have created an experiment setup to explore this phenomenon.
Brown’s system utilizes a Quantum Composers 9528 Digital Delay Generator to facilitate experiment timing. First, the pulse generator is triggered by the droplet disrupting an optical circuit consisting of a continuous laser source and a photodiode detector. Next, a suitable delay is added to allow the droplet to fall into position.
The FemtoFiber smart family is TOPTICA ’s new series of ultrafast fibre lasers. These systems are dedicated to applications ranging from biopho-tonics to terahertz generation and two-photon polymerization. Optimized for a compact footprint uniting optics and electronics in one box, these robust all-fibre lasers are the perfect choice for flexible OEM integration.
The lasers of the new FemtoFiber smart family transfer the concept of the successful FemtoFiber pro into compact systems, designed for specific ultrafast applications. Based on polarization-maintaining fibres and saturable absorber (SAM) modelocking technology, TOPTICA’s FemtoFiber lasers offer reliable performance and hands-off operation. The new FemtoFiber smart lasers are optimized re-garding footprint (122x202x69 mm3) and pricing to meet the key require-ments of OEM integrators. Including all optics and control electronics in one single box, the lasers of the FemtoFiber smart family are the most compact ultrafast lasers available on the market. All models with wavelength above 1000 nm have fibre coupled outputs and offer either FC/APC receptacles or fibre pigtails.
Flight Deck Test of CE-certified NoIR Laser Shield
High-powered hand-held laser pointers have become a significant hazard to law-enforcement officers and pilots, as they can induce a temporary and dazzling flash/glare blindness. The sudden loss of vision from even a low-power laser pointer illumination can be disorienting and debilitating, yet standard sunglasses and typical safety goggles provide virtually no protection from these hazards.
NoIRGlareShields™ laser pointer filters provide sufficient protection from the disabling effects of intentional or incidental laser pointer hits without compromising the wearer’s ability to perform on the job. All NoIR GlareShields™ provide full daylight UV and glare protection along with laser safety. But since the flash-blindness effect of a laser pointer illumination is much more pronounced at night, NoIR offers two GlareShields™ designed for use in low light conditions. GlareShields™ optimize protection from the beam with Optical Densities (ODs) between 1-2.5 (absorbing 90-99.5% of the beam energy), while still allowing visibility of the beam spot (for point source location), all without compromising visual acuity or display panel color recognition.
Ideal for Creating Line Profiles with Broadband Sources
Similar to an aspheric lens, Edmund OpticsTECHSPEC Plastic Hybrid Acylinder Lenses provide diffraction-limited focusing performance in only one dimension. By reducing spherical aberration along the focusing axis, TECHSPEC Plastic Hybrid Acylinder Lenses are ideal for creating thin line profiles. The hybrid design offers negative optical dispersion and color-correction, while the high numerical apertures allow these lenses to be used with divergent light sources such as laser diode bars and LEDs.
Thorlabs have introduced the new SDA15018, a 1500 x 1800mm version of their popular ScienceDesk workstation frame, incorporating active self-levelling isolators. The ScienceDesk frame melds function and form to produce a portable industry-leading vibration isolation platform. ScienceDesk frames feature a durable welded steel construction and the optical breadboard (working surface) is inset in the ScienceDesk frame so that it is protected from incidental contact.
The SpectroCam Multispectral Imaging (MSI) system offers a sophisticated, flexible platform for development and deployment of various MSI applications. Designed to reduce development times and simplify the design cycle , SpectroCam features a high speed, continuously rotating filter wheel containing 8 interchangeable optical filters; combined with the scientific grade CCD array, this filter design creates a fully portable, fully configurable, high speed MSI camera. With minimal pixel shift and high frame rates, this dynamic system is a powerful product development tool.
SpectroCam systems are available in a turnkey format complete with lens, 8 interchangeable filters and acquisition software that can be used for innovative 2D spectroscopy research in a variety of fields including water quality measurement, product screening, machine vision, medical imaging, surveillance and authentication. The system can also be customized for integration into specific OEM products. The platform is readily modified to meet your mechanical and environmental needs.
The ICS-15XM is the most adaptable, expandable, all-encompassing laser safety interlock system yet developed by Lasermet .
Its extended capability includes full dual channel architecture including dual safety and emergency stop circuits with separate dual channel control for each circuit. It can display up to 10 interlocks plus two emergency stop circuits. It has 9 output contacts for operating interlocks, beam shutters and door locks. It can be remotely monitored over a network and the internet with the plug-in expansion module.
The BlueMode / GreenMode / RedMode, a diode-based laser providing a stable coherence length of more than 25 m.
TOPTICA introduces active coherence stabilization scheme
TOPTICA Photonics has expanded the product portfolio of the successful BlueMode diode laser family. The new “GreenMode” and “RedMode” models transfer the original concept – high power and high coherence from a single diode – across the visible spectrum. What’s more, all models are now available in TOPTICA’s proprietary CHARM technology, a “world’s first” technique for active coherence control. TOPTICA´s BlueMode has rapidly gained acceptance in demanding laser-based inspection and metrology tasks. Researchers and engineers benefit from the combination of high power (up to 50 mW at 405 nm) and single-frequency laser operation, which is unmatched by any other direct diode-based source.
The established BlueMode wavelengths (405, 445 and 488 nm) are now complemented by new GreenMode (515 nm, 25 mW) and RedMode (638 nm, 30 mW and 685 nm, 25 mW) models. Blue/green wavelengths are well suited for Raman spectroscopy and quantum cryptography, whereas red wavelengths are a common choice in interferometry. Applications requiring multiple laser lines will appreciate the option of running two lasers simultaneously with the same set of driver electronics.
