High Resolution (-HR) spectrometers manufactured after Jan 1, 2017 should be able to be upgraded with interchangeable slits (some exceptions may apply). If you purchase a Raman-HR-TEC now you can upgrade it to have interchangeable slits at any time.
If I don’t have interchangeable slits can I upgrade my spectrometer to have them?
