For Nvidia Jetson Orin system-on-modules, E-con Systems has created a rugged waterproof camera aimed at autonomous mobility applications such as delivery robots and agriculture vehicles. SturdeCam31 is a 3Mpixel camera built around Sony’s ISX031 sensor. “Leveraging Sony’s sub-pixel HDR technology, SturdeCam31 has been tuned to provide HDR performance up to 120dB and LFM [LED flicker mitigation], thereby providing a solution ...

Texas Instruments has added an analogue version of the non-optical replacement for digital opto-isolators it just revealed. Called ‘opto-emulators’, both analogue and digital versions replace the LED and photo-diode or photo-transistor within a conventional opto-isolator with an SiO2 barrier across which the a modulated version of the input signal is passed – probably magnetically (Electronics Weekly has requested clarification). The ...

Cree LED has added higher efficiency high colour rendering index versions to its XHP35.2 leds, and introduced leds optimised to dim evenly when used in parallel The company has used its latest phosphor fill technology between the led die for improved optical performance. Optimised for indoor directional lighting, “Pro9 versions of the XHP35.2 HD and HI leds have up to ...

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 ...
