The
Lambda 10-2 is a microprocessor controlled, high speed
filter wheel. Its impressive speed coupled with exceptionally
smooth operation make the Lambda 10-2 ideal for research
applications involving fluorescence microscopy, ratio
imaging, spectrophotometry, visual physiology, or
any application requiring rapid and accurate aperture
positioning.
The Lambda 10-2 controller which has both serial and
parallel interfaces will drive up to two filter wheels
and two shutters. Each wheel can hold up to ten optical
filters (25mm in diameter and up to 9mm thick ) which
are easily loaded through an access port on the housing.
Additional filters (e.g. heat and/or neutral density
filters) may be inserted manually at two other locations
in the optical path. The optical ports on both sides
of the unit are internally threaded as C-mounts (32
threads per inch). When mounted in an upright position,
the center of the optical port can be positioned from
11cm to 53cm above the mounting surface.

Slide-in
filter holders are optionally available for inverted
configurations. A second wheel can be added to the
system with no need for additional mechanical or electronic
changes.
Eight user selectable speeds are provided. Filter
to adjacent filter time can be set from 55 to 1200msec,
depending on the number and the weight of the filters
mounted in the wheel. Integral shutter drivers will
open the optional shutter in 10msec.
The use of a direct drive stepper-motor with advanced
microstepping technology and intelligent acceleration
and deceleration algorithms assures the fastest possible
moves for a given inertial load, while minimizing
vibrations. The controller also has an error detection
and correction circuit in the event that a position
error occurs.
The controller system is designed around three embedded
controllers; one slave for each wheel and a master
for control and communication. The embedded controllers
automatically detect the equipment installed and the
source of the external commands, so there are no jumper
wires or switches to set.
The Lambda 10-2 consists of a 10-position filter wheel,
a rack mountable controller, a support base and mounting
rods, a controller/filter wheel interface cable, parallel
and serial interface cables, two drop-in filter holders,
spanner wrench, and manual. Microscope adapters for
most Nikon, Olympus, Zeiss, and Leica scopes can be
purchased separately.
For applications requiring absolute vibration isolation,
and/or spatial uniformity independent of wavelength,
an optional liquid light guide output is available
for the Lambda 10-2 wheel. The two meter long guide
mounts directly onto the output port of the wheel.
Transmission through the guide is better than 70%
from 375nm to 575nm. Adapters to connect the light
guide to your microscope port are optionally available. |

Other
Models
The
Lambda 10-2/32, was designed to remedy the problem
of vignetting that may occur with a 25mm filter format
in certain microscope systems. The system features
the same Lambda 10-2 controller but includes a ten
position wheel that accommodates 32mm diameter filters,
up to 9mm thick. The maximum filter to adjacent filter
switching speed in this system is achieved in 60 msec.
A shutter for the system is optionally available.
A T-mount format is used for mounting the wheel onto
your microscope. Contact us for information on available
T-mount adapters.
OEM wheels available
For OEM applications, the Lambda 10-2 can readily
be modified to meet your specific requirements. By
utilizing the 10-2 controller to drive customized
wheels, we can provide an economical solution to your
OEM design specification. To date we have made custom
2,3,4,5, 10 and 12 position wheels and have designed
for 50mm, 32mm and 25mm filters. Our technical staff
will be happy to discuss with you special application
requirements. |

DUAL WHEELS IN SERIES
DUAL
This option permanently modifies a two wheeled Lambda
10-2 system to allow face to face mounting of the
filterwheels in series. This modification must be
made at the factory, and requires ordering a second
filterwheel along with the basic Lambda 10- 2 system.
No drop in filters can be used in this configuration,
but one slide in filter can be used if the second
wheel is ordered with a shutter |
