A compact filter wheel with an integrated controller has been unveiled by Tofra Inc. for use with optical microscopes. It provides fast computer-controlled or manual switching of filters in the excitation or emission light path of the microscope and can accommodate 12 25-mm-diameter or 10 32-mm-diameter filters. An infrared blocking filter can be installed on the side facing the light source. The wheel can be mounted facing front or back, and mounting adapters are provided for all major microscope brands. It connects to the computer serial port via a custom cable, or to a USB port through a USB-to-serial converter. It can be used with desktop and laptop computers, and it can be daisy-chained with other filter wheels, focus drives and stages to create an automated microscope system.
