Table 2
NISP final LED parameters at 135 K.
| Channel | λpeak (nm) | FWHM (nm) | Wavelength shift (nm K−1) | Forward voltage (V) at 100 mA, 50% |
|---|---|---|---|---|
| A | 939 | 24 | 0.12 | 2.23 |
| B | 1157 | 46 | 0.14 | 1.09 |
| C | 1467 | 82 | 0.14 | 0.96 |
| D | 1735 | 129 | 0.57 | 1.68 |
| E | 1873 | 92 | 0.58 | 0.93 |
Notes. For each LED channel the peak wavelength and width are listed, as well as the shift in central wavelength with temperature in the regime around 135 K. The last column contains the characteristic forward voltage at 100 mA drive current and 50% PWM that can be used as a direct diagnostic of LED brightness, and that defines the maximal power consumption.
