9490 Series High Resolution Monochromators

The 9490 series are Sciencetech's second largest monochromators, with a 1m focal length. They can achieve resolutions as high as 0.017nm in its standard "single pass" configuration with a 1200l/mm grating. Up to twice that resolution is possible with the "double pass" configuration.

The 9490 model 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).

Each model in the 9490 series includes a single input slit. For additional options and to select the perfect grating(s) for your application, please contact us to discuss. 

The 9150 series and 9040 series of high resolution monochromators are also available.
