Note: Optical resolution (FWHM) varies by wavelength range and the size of the entrance aperture (slit width or optical fiber diameter). We define "typical" resolution as the best resolution possible over the broadest wavelength range. We recommend consulting an Application Engineer for guidance on the best approach for your application.
