The Newport 2935-C is a dual-channel optical power meter engineered for precision laser power measurement across the ultraviolet through infrared spectrum. Built for research, development, and production environments, this instrument delivers simultaneous two-channel measurement capability with true RMS support, graphical data visualization, and on-board post-processing. Its hot-swappable detector architecture and broad wavelength compatibility make it suitable for telecommunications, fiber optics, and laser system development.
