The Lambda 10-3 is a high performance,
microprocessor-controlled multi-filter wheel system for imaging applications
requiring up to 3 filter wheels. The latest generation of Sutter's optical
filter changer product line, the Lambda 10-3 uses recent advances
in motor technology to achieve switching times of 40msec between adjacent
filters. It features both USB and serial port interfaces as well as keypad
control. The Lambda 10-3 is the upgrade to the Lambda 10-2 and
ideal for imaging applications requiring multiple filter wheels. This
new release offers faster switching times, control for 3 filter wheels/
2 shutters, more communication interface options and a universal power
supply.

The Lambda 10-3 controls up to 3 filter wheels.
The user can select between one of seven speeds, allowing the speed to
be adjusted in accordance with the load of the wheel. The Lambda 10-3
can operate up to 40msec switching time speed at speed 1 with the traditional
25mm filter wheel as well as our newer, high-speed 32mm version. If additional
speed of movement is desired we manufacture a special three position wheel
which achieves switching times of less than 33 msec at speed 0.. Except
for the 4-position compact wheel, our filter wheels employ a direct drive
system consequently there is no belt slippage or backlash.
In addition the Lambda 10-3 controller supports both the traditional
Uniblitz shutter as well as our new SmartShutter line. Our SmartShutter
is designed to mount on our filter wheels much like the current shutter
is mounted so there should be no mounting constraints. In addition we
support control of a standalone SmartShutter from the controller,
making it possible to control an external SmartShutter wherever
an additional shutter is required.
The SmartShutter sets a new standard for shutter performance and
reliability. In the traditional shutter design there are two or more “leaves”
that rub against each other. Given time, the blades will wear down, bind,
and the shutter will fail to open. The SmartShutter is designed
with only one moving part, which virtually eliminates the effects of wear
and markedly improves performance. Both our 25mm and 35mm SmartShutter
are capable of opening within 8ms from the time of the trigger and can
reliably achieve repeat opening times of 20 cycles per second.
The microprocessor-based controller provides exceptional versatility and
is adaptable to various modes of operation and function. The SmartShutter
can be programmed for a variety of movement profiles or to produce a variable
aperture by determining the degree of shutter opening. When used in our
Lambda LS xenon light source and coupled with a liquid light guide, the
shutter acts as a programmable neutral density filter. While the impulse
of our shutter is minimal we have incorporated a “soft” action
mode to decrease vibration if necessary.
The command’s used to control of our new Lambda 10-3 is a
superset of the Lambda 10-2 meaning all of the commands used to control
the Lambda 10-2 . Additional commands are necessary to access the third
wheel as well as the special smart shutter features. The SmartShutter
features can be programmed through the keypad so that you can use the
old shutter commands to access the neutral density function or the soft
shutter mode.
Filter selection can be made directly from the keypad or from a computer
via the serial or USB port. The controller determines the shortest route
to the selected filter and an acceleration/deceleration algorithm minimizes
vibrations during the movement of the wheel. Internal sensors ensure correct
filter positioning and the current filter position is displayed on the
front panel. 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 PC USB port. The Lambda 10-3's USB port interface supports
multiple USB devices simultaneously, allowing a user to run in tandem
as many units as USB ports.
The line voltage for the Lambda 10-3 may be either 120 or 240 volts, 50
or 60Hz. The universal power supply will automatically switch to accommodate
the line voltage - no user adjustment is required. As with the Lambda
10-2, an optional liquid light guide is available for applications requiring
absolute vibration isolation, and/or spatial uniformity independent of
wavelength.
