The 9490 is Sciencetech's second largest monochromator, with a 1m focal length. It can achieve resolutions as high as 0.017nm in its standard "single pass" configuration with a 1200 l/mm grating. Up to twice that resolution is possible with the "double pass" configuration. This model of the 9490 allows the user to switch between the two modes seamlessly by shifting the position of a set of mirrors (easily done by rotating a single knob).
This system includes a single input slit. For additional options and to select the perfect grating(s) for your application, please speak with your Sciencetech technical sales member.
