Vishay Intertechnology has released a new series of high-speed 940nm Infra-Red (IR) emitters which offer much higher radiant intensity than standard emitters. This higher light output helps system designers to improve performance, reduce component count and cut bill-of-materials costs in new designs.
The new IR emitters benefit from Vishay Semiconductors’ SurfLight™ surface emitter chip technology. Unlike standard IR emitters, which emit light in all directions, Vishay’s SurfLight devices emit nearly all the light and power out of the top of the chip.
Since most of the light is concentrated at the surface, the emitters achieve a much higher radiant intensity, as much as five times greater than that of standard IR emitters.
Vishay supplies the IR emitters in a range of package types suited to different system designs.
The top-view devices are package-matched with Vishay’s VEMD2000X01 and VEMD2503X01 series IR detectors, while the side-view devices are matched with the VEMD2xx3SLX01 and VEMT2xx3SLX01 detectors.
Operating in a narrow spectral bandwidth around the 940nm wavelength, the emitters guarantee invisible IR radiation.
