9072S is a small 1/8m scanning monochromator. The 9072S uses plane gratings 30mm x 30mm in size and utilizes a Czerny Turner optical configuration. The 9072S is designed to be used with single channel detectors or connected to another 9072S to form a double additive or subtractive system. The base 9072S system has a triple grating turret which is computer controlled. 4-grating turret is optional.Gratings and Grating Holders (120-8512) are sold separately. The 9072S is compatible with SS80 and SS84 adjustable slits and SS-F fixed slits. Comes with the adjustable slit.It includes Sci-mono software for basic wavelength control. Our fully-featured spectroscopy package, SciSpec, is sold separately.For applications requiring better signal to noise, reduced stray light and better resolution than the standard model a double additive model (9072DA) is available. For applications requiring a tunable bandpass or notch filter light source, the double subtractive model (9072DS) is an ideal choice.
