We start high volume mass production of single emitters and small arrays for optical proximity sensors.
The VCSELs because of their small form factor, high directionality and better electrical- optical conversion efficiency, presents itself as an easy choice as a replacement to an IR- LED in any active optical sensor. The benefits the VCSEL brings allows for smaller, more cost effective packages with lower power consumption, and longer range because of narrower native divergence allowing for design into conventional proximity sensing as well as for mobile applications.
Recent technology developments and demonstration of 63% of wall plug efficiency and operation at high temperatures as high as 100 deg C, allows Princeton Optronics VCSELs to demonstrate superiority for many proximity applications and being designed in for a number of high volume applications.
Single emitters can reach output powers up to several mWs to several Watts in continuous mode and order of magnitude more in pulsed mode while maintaining industry leading efficiencies. Single emitters and arrays are offered in die sizes from 190x190um up to 500x500um and are offered at 850 and at 940nm.
