Imaging Development Systems (IDS) is offering Sony’s IMX662 1/2.45 inch 2.16 Mpixel sensor in both colour and monochrome cameras. U3-38C0XCP comes in a completely closed 29 x 29 x 17mm zinc die-cast housing with an integral C-mount lens holder. “The sensors belonging to Sony’s Starvis 2 series are designed for maximum light sensitivity,” according to IDS. “We offer this rolling ...
Hamamatsu Photonics has launched a TO-8 canned SPAD (single photon avalanche photodiode) with an in-built thermoelectric cooler. Called S16835, there are two models, which differ in the width* of their sensors: 54µm or 100µm. In standard operating conditions (25°C ambient, -20°C SPAD) typical dark currents are 15 or 60 count/s respectively (50 or 200 count/s max). Terminal capacitance and gain ...
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 ...
Panasonic has created a pair of miniature opto-mosfet relays that can handle well over an amp and need little diode current. Both have back-to-back output mosfets, so they can switch ac or dc power, and both come in 4.3 x 6.8 (including leads) x 2.2mm high (SOP4) gull-wing packaging. Days later, it revealed something similar rated at 600V AQY212G3HS can ...
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 ...
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 ...
Omron has introduced 400V and 600V 110°C versions of its G3VM photo mos isolated electronic relay family, as well as a 40V 2Ω type in the 1.5 x 2.5 x 1.3mm 4pin VSON package. With G3VM-401xY2 and G3VM-601xY2 base numbers, the 400V (120mAdc, or peak ac, continuous) and 600V (90mA) devices have typical on-resistances of 22 and 45Ω respectively with ...
Australian National University scientists have engineered a room-temperature enclosure in which to concentrate ‘exciton polaritons’ – an exotic form of energy and matter with potential for optoelectronics in transition-metal dichalcogenide monolayers, such as tungsten disulphide. The exciton polariton is a hybrid particle composed of an exciton, formed from a bound electron-hole pair, and a photon. They are “a promising platform ...
Optoscribe is sampling optical fibre to silicon photonics couplers. Branded OptoCplrLT, the devices are monolithic curved glass mirrors which turn light to direct it to or from silicon-photonic grating couplers (see diagrams). “This prevents the need for bend-tolerant fibre solutions which have some significant limitations in size and profile,” according to the company. Made using a proprietary laser writing technique, ...
There are a bunch of low cost cnc engraving machines loosely called ‘3018’ as they cut material up to 30 x 18cm, and the same parts are used in two smaller sizes down to a 1610. They are not the stiffest machines, but lots of folk are making pcbs on them. Engineer in Wonderland CNC-related blogs are indexed here Something ...
