Descripon:
The OPV302 is a Vercal Cavity Surface Eming Laser (VCSEL) packaged in a dome lens TO-46 package. VCSELs oer many
advantages in sensing applicaons when compared to infrared LEDs. These devices require substanally lower drive
currents to obtain the same amount of output power as LEDs. This feature allows VCSELs to be used in low power
consumpon applicaons such as baery operated equipment. The dome lens packaging creates a narrow beam angle from
the device. Long distance applicaons may benet from this feature as secondary opcs may be eliminated, reducing total
system cost. The OPV302 is opcally and spectrally compable with Optek’s standard detector products such as the OP800
series phototransistors, OP830 series photodarlingtons and the OP910 photodiode.
