Excitation Filter Holders are used in the pE-4000 Light Source. They allow the user to insert standard 25 mm diameter excitation filters into the optical path of the illumination system. The benefit is that the excitation light can be filtered before it is delivered to the microscope or sample, narrowing the excitation band and improving the signal to noise ratio of the image. Filter wheels are no longer required, increasing the temporal resolution and enabling the capture of high-speed events. Find out more on optical filters here.
