Crystal IS has reached 99% usable area in the 100mm diameter single-crystal aluminum nitride substrates that it is developing for UVC LED production, particularly in the 260 – 270nm germicidal range. The ultra-wide bandgap and high thermal conductivity of AlN is also applicable to RF and power devices. Its first 100mm AlN wafer was made in August last year, and ...

ICFUST: Far-UVC LED for killing germs
Silanna UV will launch a 235nm LED at ICFUST 2024, the International Congress on Far-UVC Science and Technology. SF1-3M1FWL1 is a 700mW input (30mA, 23.5V nominal) device that typically emits 3mW of UV radiation at that current. typical emission angle is 125°. Packaging is 6.8 x 6.8 x 1.38mm surface-mount. “This LED is effective for surface disinfection, air purification, medical ...
Five different IR LEDs and a photodiode in the same package for spectroscopy
Marktech had revealed the latest in its line of sensors which combine many LEDs of different wavelengths with a photodiode. MTMD142345PDT38 has five LEDs at 1.04, 1.2, 1.3, 1.46 and 1.55μm, plus an InGaAs photodiode sensitive across 600 – 1,750nm, all individually addressable and hermetically sealed into a TO-5 metal can. This short-wave infra-red (SWIR) combinations is “ideal for infrared ...
Three terminal LED modulates at 263MHz and 1.3Gbit/s
Adding a third terminal to an LED can make it 50% faster, according to researchers at the iGaN Lab, led by Professor Haiding Sun at the University of Science and Technology of China (USTC). They took the idea of driving an LED via a hybrid-T network, which combine ac and dc drive signals, one stage further, building a capacitively-coupled ac ...
Organic opto-electronics was hiding a fundamental rule
Researchers at Chiba University in Japan have uncovered a rule of organic solar cell materials that could guide their development, or at least stop people hunting for the impossible. It is that the exciton binding energy in a material is a quarter of its transport bandgap, regardless of the material. “A previously unpredicted nature of exciton binding energies in organic ...
Inolux optoelectronic components are now available from TME
Polish distributor, TME, has signed a distribution agreement with US optoelectronic component manufacturer, Inolux. Stock items include surface mount, through hole and IR leds. Surface mount coloured light emitting devices for indicators or beacons make up the largest part of the range. There are also white leds, rated up to 0.1W, with viewing ranges from a well focused beam (20°) ...
Coloured LEDs for DLP projectors
Osram is aiming at projectors based on DLP technology with a set of four high-brightness coloured LEDs. With the base part number LE xx P1MS/AS (see table below for details), there are blue, amber, deep blue and green options. Each has a 6.8 x 7.6mm footprint. “The LEDs have a very close etendue match with the 0.33inch DLP imager,” according ...
Dot matrix vehicle headlamp module uses Osram micro-LED array
Vehicle part maker Marelli and Osram have teamed up to design a headlamp module with a 20,000 pixel micro-LED array. Each pixel measures 40 x 40µm, and can be individually tuned to form different beam shapes for different road conditions. “It also provides dynamic curve light and precise glare-free high beam block-out zones to avoid blinding on-coming drivers,” said Marelli. “Furthermore ...
Coloured LEDs launch into plastic and glass fibres
OMC has developed LEDs able to couple visible wavelengths into 1mm core polymer optical fibre, or 200 micron or larger glass optical fibre. “This latest product is suitable for laboratory equipment for research purposes, test and measurement instrumentation, and data communications in industrial and medical applications,” it said. They were initially developed as a custom product for a research which ...
Push-in wiring for industrial switches and indicator lights
Distributor Live Electronics is stocking a range of push-in wiring switches and indicator lamps from Japanese manufacturer IDEC. “By comparison with traditional screw-in connectors, the devices reduce wiring times, making them ideal for new and refurbished control panels and machine builds,” according to Live. “The push-in products ensure reliable connections that withstand shock and vibration, yet are quick and simple ...
