# Infrared 940 nm (ID3:09)

## Spectral characteristics

| parameter | symbol | value [nm] |
| --- | --- | --- |
| wavelength at peak emission (typical) IF = 1000 mA per LED | $\lambda$peak | 950 |
| dominant wavelength IF = 1000 mA per LED | min | $\lambda$centroid | 940 |
| spectral bandwidth at 50 % Irel max (typical) IF = 1000 mA per LED | $\Delta \lambda$ | 37 |

## Relative spectral emission

Irel = f (λ); IF = 1800 mA; TJ = 25 °C

## Relative luminous flux

ΦE/ΦE(700 mA) = f(IF); TS = 25°C
