now enhanced by the addition of the Plessey GaN- on-Si LED product range. This will accelerate the time to market for Plessey LEDs in this region.”
Plessey’s MaGIC (Manufactured on GaN-on-Si I/C) High Brightness LED (HBLED) technology has won numerous awards for its innovation and ability to cut the cost of LED lighting by using standard silicon manufacturing techniques.
ProPhotonix releases 3D Pro Laser Green Series
New range of laser diode modules provides compact solutions for machine vision
ProPhotonix Limited, a designer and manufacturer of LED illumination systems and laser diode modules with operations in Ireland and the UK, has announced the release of the 3D PRO Laser Green Series, an extension of the structured light laser product portfolio.
The 3D PRO Laser Green series includes the 3D PRO Green, the Adjustable Focus 3D PRO Laser Green and the 3D PRO Laser Mini Green, all available in either 19mm or 10mm diameters. These direct emission green structured light lasers deliver excellent uniformity making them an ideal solution for a wide range of 3D imaging applications.
The 3D PRO Laser Green Series of 520nm structured light lasers are available in a range of output powers and with uniform line and diffractive options.
Osram introduces 940nm IR LED with 150degree beam angle
Better beam shaping, with more compact optics
Osram Opto Semiconductors is launching the SFH 4726S, a high-power member of its IR Oslon Black product family with a wide beam angle of 150degrees.
When integrated in reflector-based optics, the infrared LED (IRED) pre-shapes the light beam, concentrates it and can then focus it efficiently via other optics. As a result, smaller optics can be used, permitting generally more compact lighting solution designs. This system will replace the current conventional approach, which requires optics with a much larger optical aperture. Customers also stand to benefit, for the smaller dimensions offer much greater design freedom for lighting solutions. Another advantage of the new IRED is its high optical performance of 990mW at a current of 1A.
Like its sister IRED product, the SFH 4725S, the new Oslon Black has a wavelength of 940nm. This long-wave radiation at the red end of the spectrum is barely visible to the human eye. Even the slight red glow which can be perceived at a wavelength of 850nm rarely occurs with this version. Infrared LEDs are hence suited for discreet surveillance applications; for instance in the main hall of a bank or at border crossings.
The launch of the SFH 4726S now provides customers with another Osram product for discreet security surveillance. Other fields of application for the IR Oslon Black family include optical vehicle security systems or gesture detection for computer games.
