Gaggione has introduced a number of PMMA (acrylic) led collimators optimised for wide even beams over 50°, for both CoB (chip-on-board) and small-area leds. Aimed at small-area leds, LLC59V (right) is a 45mm diameter collimator designed to provide a 48° beam while mixing colours from multi-die emitters up to 8mm2 max without dome / 4mm2 max with dome “Its close ...

Aiming at robots in complex environments, Orbbec has created a rugged industrial RGB + depth camera that streams processed images in real-time. Built inside an IP65 enclosure, ‘Femto Mega I’ has a 1Mpixel time-of-flight sensor (but see below) plus a 120° field-of-view 4K RGB sensor, and a six degree-of-freedom inertial measurement unit. Depending on mode, depth range is from 250mm ...

German factory automation company Sick has introduced 3d inspection cameras that can measure down to 800nm. Called Ruler3002, 3004, 3010, the cameras work with fields of view down to 26.6mm. “The addition of a high-powered blue [450nm] laser enables the three cameras to achieve the rapid exposure times necessary to capture the minutest three-dimensional details,” claimed the company. They “have ...

Cree is aiming at directional lighting applications such as spotlights, premium torches and sports lighting with the XP-G4 re-work of its XP-G series of leds, increasing energy in the beam while reducing side-spill, increasing maximum drive current, and reducing thermal resistance. Update: Lens-less ‘high-intensity’ variants were announced in January 2024 It is also harking back to now-unobtainable ‘pre-PCN’ XP-G2 leds ...

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 ...

Toshiba has introduced a photo-relay in a 1.45 x 2mm package that switches on in 250μs – 50% quicker than its existing TLP3475S. The new part, TLP3476S, is in a 1.5mm high (max) S-VSON4T package, has a maximum on-resistance of 1.5Ω, can carry 400mA (ac or dc) and isolates up to 500Vrms. 3mA is the maximum LED drive needed to ...

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 ...

Sony has put a 30x zoom into its latest block-style camera. Measuring 50 x 60 x 90mm, FCB-EV9520L is built around the company’s 2Mpixel Starvis 2 1/2.8in colour image sensor. It supports 1080p (HD) 60Hz and can have a 64° horizontal viewing angle. Interfacing is over LVDS. “Thanks to the cell structure employed, this camera block delivers elevated levels of ...

Rohm is to put short wavelength infra-red LEDs and photo diodes in 1.6 x 0.8mm (1608) packages for material detection in portable, wearable and hearable devices. “As SWIR is used to detect the presence of substances and their constituent components by taking advantage of characteristics of water, ice, gases or glucose that absorb specific wavelengths, target applications include light sources ...

Five more members have joined the likes of NXP, Microchip and Renesas in the ISELED Alliance, which overlooks a system of multi-colour addressable automotive LED tape lighting, built around ICs from Inova Semiconductors. The new companies are: Blue Whale (MCUs), Lextar (automotive lighting), Liteon (LEDs), Technica (communication test and validation), Asteelflash (electronic manufacturing) and YTMicro (MCUs) – bringing the total ...
