    INFRARED LEDsLEDs enable an optimal near-infrared sensing system Today’s high-efficiency, low-cost, near-infrared (NIR) LEDs and lasers enable many commercial applications. A few straightforward formulas can help the designer approximate the performance of an NIR sensing system and then optimize it to best handle the real-world variables of a particular application, as ROLF WEBER explains.

    METROLOGYPrecision tools support critical PSS metrology from R&D through high-volume LED fabrication The different capabilities of the atomic-force microscope and the white-light interferometer are well suited to the metrology demands of high-brightness LEDs built on patterned sapphire substrates, explains XIAOMEI LI. PROCESS CONTROLAdvanced analysis and control systems could multiply yields in LED manufacturing processes Significant yield enhancements in LED fabrication can be achieved by the integration of yield analysis, fault detection and classification, and run-to-run process control, says MICHAEL PLISINSKI. DESIGN FORUMBrighter LEDs can simplify driver designs LED vendors are producing components that can operate at higher drive currents and produce more lumens, and system designers can move to a simpler two-stage driver as the number of LEDs in a fixture is reduced, explains BERNIE WEIR.LAST WORDLarge-area LED display industry faces pricing and supply challenges The LED display industry needs intelligent pricing that enables sustainable businesses, as well as a secure supply chain, including reliable LED suppliers, writes PETER PIHOS of EDG RESEARCH.
