7.2 Modes
The Lambda SC supports three modes of operation for the
Smart
Shutter.

Fast Mode:
In the fast mode the motion is optimized for the fastest open and close times,
both of which will be about 8 msec.

Soft Mode:
The soft mode offers even less vibration at the expense of slower open and
close times.

Neutral Density Mode:
In this mode the user selects the extent to which the shutter
opens. When used with the Sutter Instrument light guide system (LLG), this allows the
light output from the light guide to be attenuated without changing its wavelength or
spatial distribution. The value for opening can be selected in steps from 1 (no opening) to
144 (complete opening).
7.3 Special Considerations
The new step motor-based
SmartShutter
is made from a handful of parts, any of which can
be replaced for service. The
SmartShutter can open or close in about 8 msec., and the
mechanism is robust. The shutter blade is stopped by action of the motor rather than by
mechanical stops that might fail. Because the motion profile of the shutter is controlled by a
microprocessor, the motion can be optimized for speed or for smoothness. The
microprocessor-based controller also offers additional functions and modes of operation. If
the electronics fail the motor can be disconnected and the blade set open or closed by hand.
7.3.1 Mounting
When a 25 mm
SmartShutter
is to be mounted to a Lambda 10 filter wheel, a special version
of the
SmartShutter
is supplied which will attach directly to the slide-in filter housing. The
C-mount threads in the
SmartShutter
housing will accept the standard Sutter microscope
adapters.
