The peak wavelength of the LED used in the array, the source of the LED, the light distribution view angle (full-width half-maximal), the nominal output (in millicandelas), and the measured mean output (in milliwatts) are shown. Bold items under peak wavelength means that a full 96-array LED was constructed. In other cases, high-intensity LEDs were identified.
Mean level of LED outputs ± SEM. These values are not corrected for silicon photodiode sensor spectral sensitivity factor. ETG, ETG, Inc. (Los Angeles, CA); Nichia, Nichia Photonics, Inc. (Mountville, PA); Tron, LEDTronic Inc. (Torrance, CA). Jameco, this item originates from Ligitek Corp. (China; Ligitek QW0905-LVX3833D). Discrete LEDs for 420, 440, and 592 nm were tested but not incorporated into LED arrays. The 525- and-545 nm LEDs are both listed by Nichia as green, but the spectral ranks obtained (G for NSPG510S; H for NSPG500S) have chromaticity coordinates that indicate the associated peak wavelengths.
