Rainbow multi-channel

Rainbow Series Multi-Channel Spectrometer

Two to six Aurora-class 3648-pixel spectrometers in one housing, each covering a slice of the spectrum, with a synchronous delay device that fires all channels together. Wide range and high resolution at once — 185–930 nm at 0.08–0.22 nm in the standard configurations — with internal or external triggering for pulsed sources.
