The MKS Instruments/Newport 2936-R is a dual-channel optical power and energy meter engineered for precision measurement of CW, modulated, and pulsed laser sources across broad power and energy ranges. This instrument simultaneously acquires data from two independent optical channels, supporting photodiode, thermopile, pyroelectric, and integrating sphere detectors. The 2936-R delivers 0.0004% resolution with ±0.2% accuracy for CW measurements and ±1% accuracy for peak-to-peak, pulse-to-pulse, and integration modes, making it suitable for demanding research and manufacturing environments.
