Infra-red laser cuts power consumption
A vertical cavity surface emitting laser (VCSEL) uses lower drive currents to achieve the same power output levels as conventional infra-red LEDs.
Providing design engineers with an infra-red laser designed to improve performance in security cameras, TT electronics Optek Technology has developed a vertical cavity surface emitting laser (VCSEL) device that uses lower drive currents to achieve the same power output levels as conventional infra-red LEDs Designated the OPV330 Series, the VCSELs feature high thermal stability and low drive current, making them ideal for lower power consumption applications such as battery-operated equipment

NPN phototransistors exhibit fast response times
TT Electronics' Optek Technology has developed a series of NPN silicon phototransistors in 1206 chip packages.
According to Dave Birtalan, Vice President of Optek Technology's Components Business Unit, VCSELs offer many advantages in sensing applications in comparison to infra-red LEDs, particularly those involving security cameras.
"VCSELs can achieve much greater distances with lower power consumption than infra-red LEDs".
"Typically only eight, and even as few as four, VCSEL components are needed to replace up to 20 IR LEDs", said Birtalan.
"Because of their narrower beam, VCSELs also produce less unwanted reflections in narrow spaces, as well as better long distance visibility and clarity, making them ideal for night-time security cameras in unlit spaces".
The primary advantage of VCSEL devices compared with conventional IR LEDs is their higher apertured power output, which enables enhanced operation in many transmissive and reflective applications, Birtalan continued.
Additional applications for the OPV330 Series device include noncontact position sensing, photoelectric sensors, optical encoders and light curtains.
The flat lens lateral packaging allows the device to be used with secondary optics to create custom beam profiles, Birtalan explained.
The OPV330 VCSEL is optically and spectrally compatible with Optek's standard detector products.
The OPV330 Series is an 850nm VCSEL device.
Maximum forward peak current is 20mA, with a maximum reverse voltage of 5V.
Operating temperature range is -40 to +85C.
Typical pricing for the OPV330 Series VCSEL starts at $3.78 each in quantities of 1000 pieces, with samples available immediately.
Production quantity lead time, if stock is not available, is 6 weeks.
