Hermetic Infrared Emitting Diode
OP230 Series
Description:
Each device in this series is a gallium aluminum arsenide (GaAIAs) infrared emitting diode, mounted in a hermetic
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 applications in conjunction with the OP800 or OP598 series photosensors. The OP 231
series is mechanically and spectrally matched to OP8 00, OP593 and OP598 phototransistor s.
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 relatively even illumination over a large area. The OP231W is
mechanically and spe ctrally matched to the OP800WSL and OP830SL se ries devices.
Please refer to Application Bulletins 208 and 210 for additional design information and reliability (degradation) data.
Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for
more information.
