New High-Speed 940 nm IR Emitters Featuring SurfLight™ Technology Reduce Component Count and Solution Cost
Vishay Intertechnology broadens its optoelectronics portfolio with the release of new high-speed 940 nm infrared (IR) emitters in leaded and SMD packages. Built on Vishay’s SurfLight surface emitter chip technology, the Vishay Semiconductors devices provide up to five times greater radiant intensity than standard IR emitters to reduce component counts, improve performance, and lower solution costs.
- Offering includes one leaded 5 mm IR emitter with a parabolic lens, and eight SMD devices in 0805, PLCC-2, top-looking, and side-looking packages
- SurfLight devices emit nearly all the light and power out of the top of the chip for higher intensity than standard IR emitters
- Top-looking devices are package matched with Vishay’s VEMD2000X01 and VEMD2503X01 series detectors, while side-looking devices are matched with the VEMD2xx3SLX01 and VEMT2xx3SLX01
The Perspective:
Unlike standard IR emitters that emit light in all directions, Vishay’s SurfLight devices emit nearly all the light and power out of the top of the chip. With most of the light concentrated on the surface, higher intensity is achieved; up to an exceptionally high 600 mW/sr for the leaded emitter and from 10 mW/sr to 120 mW/sr for the SMD devices. This is up to five times greater than standard IR emitters, reducing component counts, improving performance, and lowering solution costs in a wide range of infrared illumination, data transmission, and gesture recognition applications. The SurfLight emitters combine their high brightness with narrow angles of half intensity of ± 3° for the leaded device and ± 9° to ± 60° for SMD devices. With their 940 nm wavelength and narrow spectral bandwidth, the emitters guarantee invisible infrared radiation.
Availability: Samples and production quantities of the new IR emitters are available now, with lead times of eight to 16 weeks for larger orders.
