The Newport 1936-C is a single-channel optical power and energy meter delivering precision measurements across continuous wave and pulsed laser applications. This instrument combines a 5.7-inch graphical TFT LCD display with hot-swappable detector capability, enabling rapid sensor changes without power cycling. It measures optical power, optical energy, and pulse frequency up to 250 kHz with sampling rates reaching 250 kHz and display refresh at 20 Hz.
