Motorized filter wheels are precision opto-mechanical devices designed to quickly and accurately position optical filters into the imaging path. They are widely used in microscopy, scientific cameras, astronomy imaging, machine vision, and video systems, where automated spectral selection or light intensity control is required.
Shape Optics filter wheels feature an integrated stepper motor, robust housing, and user-friendly control software, enabling reliable and repeatable filter switching for automated and high-precision imaging applications.
Both USB and RS-232 motorized filter wheel versions are available:
- RS-232 models can be operated directly via a control box or remotely through serial communication
- USB models connect directly to a PC for full motorized control
Each system is supplied as a complete ready-to-use kit, including control electronics, cables, power supply, and Windows®-based graphical user interface (GUI).
