These filter wheels are used for a host of applications, including color CCD photography, fluorescence microscopy, and photometry. Two 4" dia, wheels are available: one which accepts six 25mm filters, and one which accepts twelve 12.5mm filters.

Automation of filter sequences is available through the serial interface. A simple command language facilitates retrieving filter status and making filter selections. LabVIEW software is included, and consists of a stand-alone user interface as well as a drive which can be incorporated into your own software. The unit comes with the controller, filter housing, filter wheel, and a 5 VDC power supply, and threaded rings to hold the optics in place.
