Fixed Slit (G4212B)
The fixed slit combines the required optical functions - slit and shutter - in a
simple and compact component. The slit width is directly controlled by the
micro-processor of the instrument and is fixed to 4 nm.
In March 2011 the optical unit type of the G4212B DAD changed from "Programmable Slit
(like in the G4212A) fixed to 4 nm" to a real "Fixed Slit 4 nm". First serial number was
DEAA301100.
