Applications

  • Non-contact position sensing
  • Photoelectric sensors
  • Optical encoders
  • Light curtains Vertical Cavity Surface Emitting Laser in TO-46 Package OPV302
  • 850nm VCSEL technology
  • High thermal stability
  • Low drive current
  • High output power
  • Narrow Beam Angle The OPV302 is a Vertical Cavity Surface Emitting Las er (VCSEL) packaged in a dome lens TO-46 package. VCSELs offer many advantages in sensing applications wh en compared to infrared LEDs. These devices require substantially lower drive currents to obtain the same amount of output pow er as LEDs. This feature allows VCSELs to be used in low power consumption applications such as battery operated equipment. The dome lens packaging creates a narrow beam angle from the device. Long distance applications may benefit from this feature as secondary optics may be eliminated, reducing total system cost. The OPV302 is optically and spectrally compatible with Optek’s standard detector products such as the OP800 series phototransistors, OP830 series photodarlingtons and the OP910 photodiode. Optek reserves the right to make changes at any time in order to improve design and to supply the best product possible.
