Princeton Optronics launches VCSELs for 3D Sensing, Imaging, and Gesture Recognition
High reliability 8W array has an efficiency over 40 percent
Princeton Optronics, a US maker of VCSELs and VCSEL arrays, has announced the availability of an ultra-high reliability, 8W VCSEL array with an efficiency of over 40 percent at 60degC and a MTTF (Mean Time to Failure) of >100 years at 70degC.
According to the company, the high reliability is achieved through improved device processing and a new chip on submount mounting technology. The device is directly surface-mountable on printed circuit boards and suitable for high volume manufacturing.
A key application of this device is as an illumination source for 3D sensing or imaging in computers, tablets and cell phones. This VCSEL array can be used for either structured light or time-of-flight (ToF) applications.
The arrays can be packaged in a variety of configurations for high volume applications, very similar to LEDs. They do not require a hermetically sealed housing which reduces the packaging cost. Additionally, optics can be added to the package creating greater options for beam handling in the customer's illumination system.
Princeton Optronics is a manufacturer of high power single and multi-mode VCSELs and VCSEL arrays, and has a diverse line of products suitable for many applications including illumination, metrology, and solid state laser pumping. Princeton Optronics recently won approval for two patents (US Patent 8,675,706B2 and 8,783,893B1) for surface mounted VCSELs for illumination applications.
