The
Lambda 10-B is a high performance,
microprocessor-controlled filter wheel for
imaging applications requiring a single
filter wheel. The latest release in Sutter's optical filter changer product
line, the Lambda 10-B, uses recent
advances in motor technology to achieve
switching times of 40msec between adjacent filters. When used with 3
position wheels, the Lambda 10-B achieves
switching times of less than 33msec. It
features both USB and serial port
interfaces as well as keypad control. The
Lambda 10-B is a low-cost alternative to
the Lambda 10-2 and ideal for imaging
applications requiring a single filter
wheel.
The
Lambda 10-B can operate with switching
times as brief as 40msec with our standard
25mm filter wheel as well as our newer,
high-speed 32mm wheel. The user can select
fromseven speeds, allowing the speed to be
adjusted in accordance with the load of
the wheel. Except for the 4 position
compact wheel, our filter wheels employ a
direct drive system: a feature that
prevents belt slippage or backlash. An
optional shutter installation is also
available.

Filter
selection can be made directly from the keypad or from
a computer via the serial or USB port. The Lambda 10-B
controller determines the shortest route to the
selected filter and an acceleration/deceleration
algorithm minimizes vibrations during the movement of
the wheel. The current filter position is displayed on
the front panel. Internal sensors monitor the position
of the filter wheel to insure that the correct filter
is in place. The drive uses switching mode current
regulation, which is more economical than the linear
supply of the Lambda 10-2. Although this is not a
problem with most imaging applications, the Lambda
10-2 may be more appropriate for systems where
electrophysiology is performed.
Both serial and USB input ports are provided to allow
complete and easy control from a remote computer. The
serial port accepts RS232 level signals through a DB-9
connector. USB input is made through a standard
connector and can be directly connected to a USB port.
The Lambda 10-B's USB port interface supports
multiple USB devices simultaneously, allowing a user
to run in tandem as many units as USB ports. The
universal power supply will automatically switch to
accommodate local line voltage.
