1.5.2 Modes

The LAMBDA 10-B supports three modes of operation for the SmartShutter.
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:

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).

1.5.3 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 milliseconds, 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.

1.5.3.1 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.
When a 35 mm SmartShutter is mounted to a 32 mm Lambda 10 series filter wheel, a special
adapter threads into the filter wheel T-mount, on which the SmartShutter is mounted. The
35 mm SmartShutter has a receptacle for the flange on the end of this T-mount tube and this
allows the SmartShutter to mount to the flange on the end of the tube in many different
orientations. On the other side of the SmartShutter a similar rotating mount accepts an
In this mode the user selects the extent to which the shutter
