2.5 Internal Shutter
The IsoPlane has an optional internal shutter. If the shutter is installed, it
is located in the Turret Compartment and is mounted to the
spectrograph wall. Its shutter cable plugs into a keyed 2-pin shutter
connector in the floor of the IsoPlane. The external connector is
below the detector mounting plate and can be connected via a shutter
cable to a detector with a SHUTTER connector. If a detector does
not have a SHUTTER connector (PI-MAX detectors, for example),
the Princeton Instruments SHC-EXT Shutter Control Box can be
used to control the opening and closing of the internal shutter. If the control box is not available,
the internal shutter can be removed. Instructions for installing and removing the internal shutter
assembly are provided in Sections 2.13.1 and 2.13.2, respectively.
