Princeton Optronics, industry recognized leader in high efficiency, high power VCSELs and VCSEL arrays, announces the start high volume mass production of single emitters and small arrays for autofocusing for cameras for cell phones and tablets.

The VCSELs because of their small form factor, high directionality and better electrical to 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 light source for camera autofocus in 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 as 100 um thick dies with sizes from 175 x 175 um up to 500 x 500 um and are offered at 850 and at 940 nm.

Princeton Optronics is a manufacturer of high power single and multi-mode VCSELs and VCSEL arrays, and products using VCSEL devices and arrays. It has a diverse line of products suitable for applications including illumination, Lidar, sensing and solid state laser pumping.
