Predicted Ranges & Resolution: HR Benches

These graphs demonstrate the range and resolution of the HR4000 Spectrometer and the HR2000 Spectrometer each with a 5 µm Slit and various gratings.

Range & Resolution Charts for the HR4000 Spectrometer

Example: If the starting wavelength is 400 nm, then the range is ~437 nm, providing a 400-837 nm wavelength range and 0.239 nm optical resolution (FWHM). Gratings for the HR Bench that have groove densities of 600 mm-1 are Grating H1, H2, H3, H4 and H14.
 

Example: If the starting wavelength is 300 nm, then the range is ~215 nm, providing a 300-515 nm wavelength range and 0.117 nm optical resolution (FWHM). Gratings for the HR Bench that have groove densities of 1200 mm-1 are Grating H5, H6 and H9.
 

Example: If the starting wavelength is 700 nm, then the range is ~90 nm, providing a 700-790 nm wavelength range and 0.05 nm optical resolution (FWHM). Gratings for the HR Bench that have groove densities of 1800 mm-1 are Grating H10 and H11.
 

Example: If the starting wavelength is 600 nm, then the range is ~56 nm, providing a 600-656 nm wavelength range and 0.029 nm optical resolution (FWHM). Gratings for the HR Bench that have groove densities of 2400 mm-1 are Grating H7 and H12.

 

Range & Resolution Charts for the HR2000 Spectrometer

Example: If the starting wavelength is 400 nm, then the range is ~437 nm, providing a 400-837 nm wavelength range and 0.32 nm optical resolution (FWHM). Gratings for the HR Bench that have groove densities of 600 mm-1 are Grating H1, H2, H3, H4 and H14.
 

Example: If the starting wavelength is 600 nm, then the range is ~188 nm, providing a 600-788 nm wavelength range and 0.137 nm optical resolution (FWHM). Gratings for the HR Bench that have groove densities of 1200 mm-1 are Grating H5, H6 and H9.
 

Example: If the starting wavelength is 700 nm, then the range is ~90 nm, providing a 700-790 nm wavelength range and 0.065 nm optical resolution (FWHM). Gratings for the HR Bench that have groove densities of 1800 mm-1 are Grating H10 and H11.
 

Example: If the starting wavelength is 600 nm, then the range is ~56 nm, providing a 600-656 nm wavelength range and 0.039 nm optical resolution (FWHM). Gratings for the HR Bench that have groove densities of 2400 mm-1 are Grating H7 and H12.
