When a 35 mm
SmartShutter
is to be mounted to a 32 mm Lambda 10 filter wheel, a special
adapter threads into the filter wheel T-mount and the
SmartShutter
mounts on this piece.
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
adapter that is used to couple to our standard microscope adapters. It is possible to install a
T-mount instead, if desired.
7.3.2 Opening and Closing Times
The
SmartShutter
has a typical time to open of 8 msec. from the point a complete command
or TTL signal is received. The time to close is also 8 msec. This is true for both the 25 mm
and the 35 mm versions operating in the fast mode. Note that the controller will not accept
new commands or TTL pulses in the FAST mode for about 12 msec after a command has
been received. The additional time is required for display changes and other overhead.
Figure 7-3. SmartShutter timing
The previous figure shows the timing of a
SmartShutter
. The bottom trace is a TTL signal,
the middle trace is a 25 mm
SmartShutter
, and the upper trace is a 35 mm
SmartShutter
.
Operation is slower in the ND (Neutral Density) and SOFT modes. In the SOFT mode, the
SmartShutter
has a typical time to open of 60 msec. from the point a complete command or
TTL signal is received. The time to close is also 60 msec. This is true for both the 25 mm and
the 35 mm versions. In the ND mode the time to open and the time to close will depend on
