NuTx: Pulsed Fiber Laser Transmitters

LIDAR and LADAR Sources

[NuTx photo]NuTx™: An emerging line of compact and high-efficiency eye-safe light sources for LIDAR and LADAR applications. Powered by Nufern's patented LMA optical fibers, this product family excels in delivering high peak power, high beam quality pulses. Designed with monolithic fiber architecture and Nufern's fiber packaging expertise, NuTx transmitters are highly resistant to shock and persistent vibration. These sources enable high-resolution imaging technology while minimizing stray light and detectability.
