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 mechanical interfacing of the wheel accepts SM1 (1.035"-40) lens tubes and 30 mm cage systems for both input and output ports of the filter wheel housing. The housing contains an 8-32 (M4) tapped hole to allow post mounting of the wheel. Up to six Ø1.0" (Ø25 mm) filters mounted in the standard housing (e.g., Thorlabs' FEL series) can be fitted onto the wheel. Access for the fitting of filters can be gained through a removable cover without needing to unmount the filter wheel from the optomechanical setup within which it sits.
The FW103H includes the filter wheel and our BSC201, Single-Channel apttm Controller for applications requiring high-speed switching (55 ms) between 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. 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.
