New Advanced Benchtop Optical Power & Energy Meter, Dual Channel

1940-R and 2940-R Benchtop Optical Power Meters

The Newport™ 2940-R optical power meter is a high-precision, dual-channel benchtop instrument engineered for fast, accurate, and stable photonics measurements in R&D laboratories and high-volume production environments, including active fiber alignment. Each meter is shipped with a NIST-traceable calibration certificate (ISO/IEC 17025 accredited), a quick-start guide, and a power cord.
