Princeton Optronics, the recognized leader in high efficiency, high power VCSELs and VCSEL arrays, announces the availability of high power (8W) 940nm arrays for illumination applications. These arrays have an efficiency of >45%, a spectral width of approximately 1nm and a circular beam with divergence of 18 degrees (full angle). The array is of the size of 2x2mm and is normally mounted on submounts. The solar background rejection capability stems from the sharply lower level of solar background and use of narrow band filters for the detector arrays at 940nm compared to wavelengths such as 800 or 850nm.

Princeton Optronics also deliver single devices and lower power arrays at 940nm with power level of tens of mW to several watts as well as addressable arrays. A very high power array of >100W at 940nm is under construction for pumping application. Princeton Optronics can make custom devices and arrays at this wavelength as well as at other configurations and other wavelengths. 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, sensing and solid state laser pumping.
