Grating Efficiency Curves Predicted Ranges & Resolution
Below are the Grating Efficiency Curves for gratings withgroove densities of 600, 1200, 1800 and 2400 mm These graphs demonstrate the range and resolution of your“QE”Bench Spectrometer with a 5 µm slit. See our websitefor more graphs of ranges and resolutions for every slit size.
