The OD-669-850 high-power, gallium aluminum arsenide, IR light-emitting diode illuminator from Opto Diode is suited for night vision illumination tasks. The illuminator features ultrahigh optical output, from 800 (minimum) to1250 mW (typical), and a peak emission wavelength of 850 nm. The device provides a highly uniform optical beam. The spectral bandwidth at 50% is typically 40 nm, and the half-intensity beam angle is 120°. All surfaces on the standard two-lead, TO-66 electrically isolated package are gold plate. The illuminator’s operating and storage temperatures range from −40 to +100°C with a maximum junction temperature of 100°C.
