A longer front for the MAC 600 that narrows the field angle from 25° to 18° is available. This part comes with the Fresnel lens and may be ordered as P/N 91610005.
The MAC 600 with this longer front will not fit in older MAC 600 flight cases. One must use the new MAC 500/600 flight case. Flight cases can be identified by measuring from the ground to the top corner: old flight cases measure 860 mm (34"), and new flight cases measure 894 mm (35.2"). There are also a few prototype flight cases that will can hold the MAC 600 with the long lens front. These measure 880 mm (34.6").
