1.1 Introduction
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.
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.
Choice of electronic controller for the FW103 depends on the required speed of
operation. The FW103H kit includes the FW103 filter wheel and our BSC201 single-
channel controller, for applications requiring high-speed switching (<50ms) between
adjacent filters.
Where slower speed filter switching is desired (~250ms), the filter wheel can be driven
by our KST101 K-cube stepper motor controller. The KST101 controller offers two
power supply options each sold separately: KPS101 when using a single KST101 K-
Cube and the KCHxxx hubs for up to 6 K-Cubes.
