Web10 The effect of the objective is that of a low-pass filter, with the cut-off frequency in 1D given by 2 2 M M Ob M kx f , (0.6) M is the maximum angle subtended by the entrance pupil from the specimen. Qualitatively, this low-pass filter has the effect of smoothing-down the details in the sample field, i.e. limiting the spatial resolution of the instrument. WebThe filter wheel is rotated so that there is a 400 nm long pass filter in front of the exit slit which transmits the desired 600 nm light while blocking the unwanted 300 nm light (right image).
