High-power IR LEDs boast high efficiency
Infra-red LED light sources are designed for applications that require high reliability and long-term stability.
A newly available range of infra-red (IR) LED light sources from OSA Opto Light are designed for a range of applications that require high reliability and long-term stability These high-power GaAlAs (gallium aluminium arsenide) devices are available in SMD packages or bare dice for chip-on-board use, and feature high external quantum efficiency and an emission spectrum without secondary emission peaks

LEDS offer high efficiency
OSA Opto Light (OSA) has released the OLS 330 and OCL 400 LEDs, with a 1206 SMD with lens and a white ceramics package.

Agilent Technologies has introduced a series of surface-mount LEDs designed and qualified specifically for automobile interior and exterior lighting applications.
High-output blue LED has power to replace arrays
New from AP Technologies is the OD-470 high-output blue LED with a typical emission wavelength of 470nm and output power of 30mW DC.
Biotechnological, medical, industrial and laboratory test and measurement applications commonly require such radiant IR sources to enable spectroscopy, absorption measurements or illumination of machine vision work-areas.
OSA's substrateless chips provide emission wavelengths ranging from 660 to 940nm, selectable in 10nm steps.
Devices are 100% tested, to ensure tight conformance of peak and centroid wavelength, half-width and radiant intensity, and absence of secondary peaks.
A range of off-the-shelf options and custom solutions can be realised with rapid turnaround.
These include variants with integrated lens, intensity-controlled secondary emission at 880nm, and a broad range of chip layouts with chip edge length between 300 and 2000um, allowing electrical power dissipations of up to 2W.
All designs can be supplied with solderable back side.
SMD-packaged devices are available with a viewing angle of 120 degrees as standard, and, for versions with a lens, of 40 to 50 degrees.
Further standard packages include 1206-types, available with or without lens, 0805-types, and side-view devices.
All variants conform with RoHS and are lead-free reflow solderable.
