Descrip on: 

Each device in this series is a gallium aluminum arsenide (GaAIAs) infrared emi ng diode, mounted in a herme c metal TO‐

46 housing. The gallium aluminum arsenide feature provides a higher radiated output than gallium arsenide at the same

forward current.

Each OP231, OP232, OP233, OP234 and OP235 device is lensed to provide a narrow beam angle (18°) between half power

points. The 890 nm wavelength closely matches the spectral response of silicon phototransistors, while the narrow beam

angle – combined with the specified radiant intensity of the OP231 series – facilitates easy design in beam interrupt

applica ons in conjunc on with the OP800 or OP598 series photosensors. The OP231 series is mechanically and spectrally 

matched to OP800, OP593 and OP598 phototransistors.

Each OP231W, OP232W, OP233W, OP234W and OP235W device is lensed to provide a wide beam angle (50°) between half

power points. The 890 nm wavelength closely matches the spectral response of silicon photo‐transistors, while the wide

beam angle provides rela vely even illumina on over a large area. The OP231W is mechanically and spectrally matched to 

the OP800WSL and OP830SL series devices.
