Introducing the USB Filter Wheel

The Picard USB optical filter wheel offers a small, quiet and simple motorized method of automating the selection of up to six different filters at a relatively low cost. The unit comes complete with a 3 meter USB cable and Windows software, which runs on any standard PC with a Windows-NT/XP/VISTA operating system with a USB port. The USB port provides the means to power and control the filter wheel. It provides a self-powered method of motor control that is unmatched in size, simplicity, and cost.
