The Newport 2930-C is a dual-channel optical power meter designed for simultaneous measurement of two independent optical signals across UV through near-infrared wavelengths. It delivers measurement ranges from tens of femto-Watts to 2.5 W with 131 dB dynamic range when equipped with an attenuator, making it suitable for precision power characterization in scientific research, telecom, and datacom laser applications.
