Princeton Optronics

Princeton Optronics develops and manufactures VCSEL type of diode lasers and VCSEL based optical subassemblies for various applications such as 3D depth cameras, LiDARs, IR illumination, medical, pumping of solid state lasers and many other diode laser applications.

About Us

Located in Mercerville, NJ, Princeton Optronics is a developer and manufacturer of high efficiency, high and low power vertical cavity surface emitting diode lasers (VCSELs), VCSEL-based optical subassemblies and modules, as well as diode pumped solid state lasers and visible lasers with direct frequency conversion. Princeton Optronics was founded in 1993 and has since been working in various cutting edge technology areas.

Princeton Optronics is located in a 30,000 square ft facility, which has over 1000 square ft of clean room space for device fabrication and 10,000 square ft dedicated to optical manufacturing . We also have a fully equipped reliability and qualification facility for our products many of which are used for US military applications.

While we manufacture low volume, quick turn-around products for our customers from our Mercerville VCSEL fabrication and assembly facility, for high volume manufacturing of our products, we use outside fabs and assembly facilities located in USA and Taiwan to provide the most cost efficient high volume products to our customers.

Our breakthrough research in Vertical Cavity Surface Emitting Diode Lasers leading to highest efficiency, highest reliability and highest speed devices, as well as diode pumped solid state lasers, and frequency doubled diode lasers, has been conducted with significant funding support of various organizations of the Department of Defense. This support along with our investor funding is is moving the VCSELs to the next level of market acceptance.

Since July 2017 Princeton Optronics has become a member of the ams group. ams is a global leader in the design and manufacture of advanced sensor solutions. With headquarters in Austria, ams employs around 7,000 people globally and serves more than 8,000 customers worldwide. ams is listed on the SIX Swiss stock exchange (ticker symbol: AMS).
