Motorized Fast-Change Filter Wheel![]()
FW103H Motorized Filter Wheel BSC201 High-Speed Switching Controller Application Idea Compatible with Our Ø1/2" Posts, ![]() Please Wait
Features
This motorized fast-change filter wheel has been designed for applications that require sequential observations with different filters inserted in the optical path, such as multi-wavelength fluorescence imaging. The optical port is internally SM1 (1.035"-40) threaded on both sides for compatibility with our Ø1" lens tubes, and each side contains four 4-40 taps for compatibility with our 30 mm cage systems. The perimeter of the housing contains four 8-32 (M4) tapped holes at 90° spacings to allow the wheel to be mounted on Ø1/2" posts. Up to six Ø1" (Ø25.4 mm) filters mounted in the standard housing (e.g., Thorlabs' FEL series) can be fitted onto the wheel. A removable cover allows filters to be installed without needing to unmount the filter wheel from the optomechanical setup within which it sits. The FW103H(/M) includes the filter wheel and our BSC201 Single-Channel APT™ Controller, which provides a switching time between 55 - 60 ms for adjacent filters. The BSC201 comes with a power supply for 110 to 240 V and with a US, UK, or European power cord determined by your ordering location. The filter wheel can also be used with the KST101 K-Cube™ controller, but the switching time will increase to 250 ms. If you are interested in this option, please contact Technical Support to inquire about purchasing a filter wheel without the BSC201 controller. The filter wheel uses a Hall effect sensor to determine the filter wheel's position, which is ideal for light-sensitive applications. The Motorized Fast-Change Filter Wheel can hold up to six Ø1" filters, which can be easily inserted into the wheel in three steps.
