INFRARED EMITTERS
Sur fLight™ Series
SurfLight™ - High Power IR Emitter
Vishay’s SurfLight™ surface emitting technology is redefining performance standards for
infrared emitters. With SurfLightTM, 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 - and that means fewer emitters are needed, lowering the total system
cost of your application.

INFRARED EMITTERS
Sur fLight™ Series
FARTHER WITH FEWER
Vishay’s SurfLightTM 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.
