LED Lights with Symbol Marking

Wilbrecht LEDCO (St. Paul, MN) has added symbol/legend marking options to its 100/600 series of panel LEDs for custom applications. Custom and universal symbols, such as battery light or oil level, can be used for easy identification. A simple stamp printing process allows a pictogram or short word to be printed in white or black ink on blue, green, amber, red and clear lenses. The LEDs can be selected in 3 intensities- High Efficiency, Daylight readable super bright, and super ultra-bright. Available in prototype to production quantities, the led indicators are built with standard DC LEDs or bipolar LEDs for AC applications. By adding a simple resistor, they can be operated at 5-60VDC or up to 240VAC. www.wilbrechtledco.com/

Scientists Unlock Secret of Ultrafast Imaging of Complex Systems in 3-D at Near Atomic Resolution

It is becoming possible to image complex systems in 3-D with near-atomic resolution on ultrafast timescales using extremely intense X-ray free-electron laser (XFEL) pulses. One important step toward ultrafast imaging of samples with a single X-ray shot is understanding the interaction of extremely brilliant and intense X-ray pulses with the sample, including ionization rates.

Laser-Generated Surface Structures Create Extremely Water-Repellent Metals

Scientists at the University of Rochester have used lasers to transform metals into extremely water repellent, or super-hydrophobic, materials without the need for temporary coatings. Super-hydrophobic materials are desirable for a number of applications such as rust prevention, anti-icing, or even in sanitation uses. However, as Rochester’s Chunlei Guo explains, most current hydrophobic materials rely on chemical coatings.

Thermal Imaging Camera

The FLIR Systems (Meer, Belgium) A6700sc features a highly sensitive 640x512 pixel resolution Indium Antimonide (InSb) detector that produces temperature- calibrated IR imagery for research and science applications. A6700sc cameras have been designed to stream temperature-calibrated data over Gigabit Ethernet to a PC for live image viewing and recording. Using FLIR’s ResearchIR software, researchers and scientists can monitor, acquire, analyze, and share data. In addition, extender rings for zoomed-in fields of view make the camera perfect for imaging small thermal targets, and close-up lenses can detect spot sizes down to 15um per pixel. www.FLIR.com

NIR Single Photon Counting OEM Module

AUREA Technology (Besancon, France) has launched its newly designed fast Near Infrared (NIR) [900 nm-1700 nm] Single Photon Counting OEM Module, SPD_NIR_OEM_120MHz. Due to its Geiger-mode InGaAs avalanche photodiode SPAD and its new enhanced embedded electronics, it provides gated-mode operation up to 120 MHz trigger rate with very fast timing resolution < 150 psec. The SPD_NIR_OEM_120MHz performs very-low-noise DCR www.aureatechnology.com

Pyroelectric Detectors

LASER COMPONENTS Pyro Group (Olching, Germany) produces pyroelectric DLaTGS detectors - three series are available: One for users who would like to combine their detectors with their own electronics (LCDT-5000 series); the LCTDT-5100 series is designed for low-fre¬quency applications in the range of 10-100 Hz, and the LCDT-5500 type with a low-noise JFET is designed for FTIR applications. All detectors possess thinned-out ele¬ments and optionally feature an absorbing black coating with a low thermal mass that offers a wide spectral response at a simultaneously high speed. All pyrodetectors are available with different diameters of their active surfaces and rectangular and square shapes as well. Standard housings include TO-5, TO-66, and TO-37. www.lasercomponents.com/de-en/ir-components/ir-detectors/pyroelectric-sensors/

Four-Channel Intelligent LED Controllers

Saelig Company Inc. (Fairport, NY) has announced the LED-Warrior04, a 4 channel, intelligent, programmable LED constant-current driver with DALI, DMX512, and I2C interfaces on board. Other bus protocols or wireless options can be added via the I2C interface. For each of the four channels, the forward current and brightness of the LEDs can be individually and independently programmed. Current can be programmed from 80 mA to 1000 mA in 5mA steps. Brightness is controlled by internal 12-bit PWMs for each channel, allowing 4096 steps, with dimming down to 1/4096 or 0.024%. The high resolution of brightness control allows precise color mixing or calibration of multiple LED groups. The four 12-bit channels allow up to 281 trillion color hues. www.saelig.com
