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 Laser (VCSEL) packaged in a dome lens TO-46 package.
VCSELs offer many advantages in sensing applications when compared to infrared LEDs. These devices require
substantially lower drive currents to obtain the same amount of output power 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.
