Can all lines be used in multi element lamps? Is there any spectral interference?
All the usual primary lines may be used with Varian multi-element lamps. The primary lines have been checked for spectral interference and minimal or no interference has been noted. The secondary lines have not been checked and for this reason only, the use of secondary lines is not recommended. Where there are interferences, the use of Varian UltrAA (high intensity boosted discharge) lamps can help to minimize these effects.
