SurfLight Surface-Emitting Technology

Vishay’s SurfLight™ surface-emitting technology is redefining performance standards for infrared emitters. With SurfLight, nearly all the light and power is emitted out the top of the chip, unlike standard infrared emitters that emit their light in all directions. With most of the light concentrated on the surface, you get higher-intensity, up to five-times greater than standard emitter technology. In effect fewer emitters are needed, lowering the total system cost of your application.

Vishay’s SurfLight series allows you to reduce the number of infrared emitters required for your application by up to 80% while achieving the same resolution and range. Illumination applications include closed-circuit television (CCTV), security cameras, and CMOS image sensors. For data transmission in museums, concert halls, and other public venues, these emitters feature switching times from 10 ns to 20 ns, meeting the requirements for high-modulation operation and supporting data transmission rates of up to 16 Mbit/s.
