The OP233 is a gallium aluminium arsenide (GaAIAs) Infrared Emitting Diode, mounted in a hermetic metal housing. The gallium aluminium arsenide feature provides a higher radiated output than gallium arsenide at the same forward current. The device is lensed to provide a narrow beam angle (18°) between half power points. The 890nm wavelength closely matches the spectral response of silicon phototransistors.
Focused and non-focused optical light pattern
Enhanced temperature range
Mechanically and spectrally matched to other OPTEK devices
