Large Capacity Filter Wheel with Integrated Controller

Large Capacity Filter WheelLarge Capacity Filter WheelLarge Capacity Filter WheelLarge Capacity Filter Wheel 

Large Capacity Filter Wheel with Integrated Controller is designed for changing filters in the light path of optical systems, including microscopes.  The filter wheel provides fast computer controlled or manual switching of filters. It can accommodate either 22 filters, 25mm in diameter, or 18 filters, 32mm in diameter. The filters could be up to 8 mm in thickness. 

The wheel can be used as part of automated optical systems. It has a simple, cost-effective and highly reliable construction. The wheel is compact in size.  It is 17mm thick, maximum outside dimension of the housing is 236 mm. The case is made of 1/8” aluminum and is very rigid. A knob with filter numbers is mounted on the front of the motor. Current active filter corresponds to the number closest to the controller box.  If the wheel is not powered, the knob can be used for manual filter positioning. The wheel does not need any additional control units; it connects directly to the computer serial or USB port via a cable with built-in converter.

The key feature of the design is direct drive. Filter wheel is mounted directly on the motor shaft. A stepping motor with 200 steps per revolution is driven by a microstepping controller. A built-in optical switch is used to home the wheel after power up or as needed. Time required to switch between the adjacent filters is under 200 milliseconds. Switching time depends on parameters of the wheel controller.

Mounting adapters are provided for the major microscope brands. Front and back adapters are interchangeable, so the wheel can be mounted in forward or reverse orientation.  Adapters for new microscopes can be custom-made and usually do not carry additional charges.
