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.
Remote or Manual Operation
Filter selection can be made manually from push buttons on the unit, or remotely from either a USB 2.0 interface, or a BNC input. The BNC input accepts a TTL level signal to trigger the rotation of the filter wheel.
Interchangeable filter wheels
The 4" dia. wheel is easily changed, allowing quick conversions between applications. Additional wheels are available.
Programming and Remote Control
Automation of filter sequences is available through the USB 2.0 interface. A simple command language facilitates retrieving filter status and making filter selections. 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.

Of course you will want filters to fill these wheels. Andover offers you the opportunity to build your own filter sets from across our product listings–whether bandpass, neutral density, dichroic, edge, or other filter category. The only restriction is that the filters must be the same size. Take your choice of six and twelve-piece sets in one of two standard sizes. All filter sets include complete spectral data and are shipped in a hardwood storage case. Get all the details here.
