from Sutter Instrument Co. This post, along with posts of other dimensions, as well as post
holders and bases, are available from most laboratory equipment suppliers.
A SmartShutter can also be mounted on a Sutter Instrument Co. Filter Wheel with a special
enclosure, as well as with other Sutter Instrument Co. products, such as the Lambda LS,
Lambda DG-4, Lambda DG-5, and various Lambda 10 series Filter Wheel controllers. Please
consult with Sutter Instrument Co.'s Technical Support for the different configuration
possibilities.
1.3.7 Cables
A special cable is required for connecting one or two standalone SmartShutters. The CIQ-2
cable is a split cable consisting of one DB-25 connector at the main end (for connecting to the
"SmartShutter" connector on the rear of the LAMBDA 10-B cabinet) and a DB-9 connector
at each of the split ends. One split end is shorter than the other. When connecting a single
standalone SmartShutter to the LAMBDA 10-B, the SmartShutter connects to the DB-9
connector of the longer split, and a terminator is required to be attached to the DB-9
connector of the shorter split.
1.3.8 Devices for TTL-Control of Shutters
Two devices are available for the TTL control of shutters that are attached to the LAMBDA
10-B.
FSWITCH:
A foot switch with BNC connector. It changes the ON/OFF state of the
shutter with each foot press. The state is maintained if the switch remains
depressed.
FSTOGGLE:
Like the FSWITCH but alternates the ON/OFF state with each foot press.
1.4 Adapters
Most microscopes, cameras, light sources, and other optical instruments to which the
LAMBDA 10-B Filter Wheel may be interfaced will require some sort of adapter to link the
devices. Adapters for interfacing the Filter Wheel to most instruments are available from
Sutter Instrument Company or can be custom built by Sutter Instrument. Suitable adapters
are available from other sources, as well, but Sutter Instrument Company assumes no
responsibility for the performance, suitability, and safety of adapters built by the user or
other manufacturers.
1.5 SmartShutter
The SmartShutter is a lightweight motor-driven aluminum vane under microprocessor
control. Because of the microprocessor control, the motion of the vane can be tailored for
different roles. The vane starts and stops under motor control, eliminating the sharp jolt
typical of other fast shutters.
1.5.1 Step Motor Based Shutter Advantages
The new step motor-based shutter is made from a handful of parts, any of which can be
replaced if it fails. The speed of opening and closing of the shutter is practically the same as
the traditional shutters, and the mechanism is more robust. The shutter blade is stopped by
