What Are Filter Wheels?
Filter wheels are used to selectively transmit light of specific wavelengths.
These devices consist of multiple circularly arranged filters, which allows for different filters to be inserted into the optical path by rotating the wheel. This feature enables the rapid selection of light of different wavelengths, facilitating efficient data collection and image acquisition.
Filter wheels can be controlled manually or electronically, with many models supporting remote operation. They are crucial in fields requiring precise filter switching, such as optical experiments, astronomical observations, and microscope inspections, where accuracy and speed are paramount.
