OPV320, OPV320TX, OPV320TXV
850NM VCSEL technology
High thermal stability
Low drive current
High Output power
Narrow Beam Angle
The OPV320 is a Vertical Cavity Surface Emitting Laser (VCSEL) packaged in a flat lens pill package. VCSELs
offer many advantages in sensing applications when compared to infrared LEDs. These devices require substan-
tially 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.
TX and TXV versions are processed per MIL-PRF-19500.
The flat lens packaging allows the device to be used with secondary optics to create custom beam profiles. The
OPV320 is optically and spectrally compatible with Optek’s standard detector products such as the OP600 series
phototransistors, OP300 series photodarlingtons and the OP900 series photodiodes.
For custom processing and or opto-electrical characteristics, contact your OPTEK sales representative.
Non-contact position sensing
Additional laser safety information can be found on the Optek website. See application bulletin #221. Classification is
not marked on the device due to space limitations. See package outline for centerline of optical radiance. Operating
devices beyond maximum rating may result in hazardous radiation exposure.
