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 TST001 T-Cube controller, but the switching time will increase to 250 ms. 

The filter wheel uses a Hall effect sensor to determine the filter wheel's position, which is ideal for light-sensitive applications.

Remove the housing cover to gain access to the six filter slots (individual filters can be changed by using the filter access cover located on the housing cover, shown to the bottom left)

Step 2

Filter Installation

Insert the filter into the desired port of the filter wheel

Step 3

Filter Installation

Secure the filter's position using one of the provided retention rings and three screws (M2 x 8 for 6.35 mm filter or M2 x 6 for thinner filters) as shown above
