Versatile Computer Controlled Filter Wheels

AB300-T
A six position wheel that integrates with SP's popular Digikröm and meter monochromators. Plugging directly into the Digikröm, resident software commands allow easy manipulation to filter higher order energy. It can also be controlled by your hand-held controller. The AB300 uses 1" diameter filters.

AB301-T
A stand-alone, six position 1" filter wheel that is stepper motor controlled via USB2.0 and can be used with SP's 1/8 meter compact monochromators for order sorting purposes.

AB302-T
A stand-alone, five position 2" filter wheel that is ideal for LIDAR applications. Stepper motor controlled, it can be combined with AB301-T's, AB302-T's, or AB303-T's in multiple filter wheel systems.

AB303-T
A stand-alone, twelve position 1/2" filter wheel that is stepper motor controlled. Ideal for multiple monochromatic illumination applications.

AB304-T
A stand-alone, twelve position 1" filter wheel that is stepper motor controlled. Ideal for multiple monochromatic illumination applications.

Inexpensive Monochromators
When used with narrow-band interference filters, you can select up to twelve specific band-passes for monochromatic illumination. This provides maximum throughput with excellent stray light rejection.

Applications
Not only are these filter wheels ideal for use with monochromators, spectrographs and spectrophotometers, but they can be easily integrated with microscopes, flow cytometers, fluorimeters, and fluorescence photometers. Neutral density filters will allow for photometric linearity and dynamic range studies. Modern communication multiplexing capabilities provide the capability of combining any number of these filter wheels together in an integrated system. Call with your custom or OEM requirements.
