The VSMY98545 series, from Vishay Semiconductors, are high power IR emitting diodes. These surface mount (SMT) devices has a dome shaped moulded lens containing a 42 mil chip.
Suitable applications for the VSMY98545 series include; machine vision, camera illumination (3D gaming) and IR illumination for CMOS cameras.

Features of the VSMY98545 series:
Dimensions: 3.85 x 3.85 x 2.24 mm
Peak wavelength: 850nm
High reliability
High radiant power
Beam angle: 90°

SurfLight™ series, from Vishay Semiconductors, consists of high power Infrared (IR) emitters. Their SurfLight™ technology enables the majority of the light and power to be emitted directly through the top of the chip. Standard IR emitters send their light in all directions.
SurfLight™ technology therefore offers a higher intensity output of light. A higher intensity can reduce the number of emitters required for a design. This series also offers high speed with a high pulse current operation.
The reliable SurfLight™ IR LEDs are ideal for applications such as IR data transmission or communication, 3D TV glasses synchronisation, automotive, industrial and IR illumination for CCTV cameras.
