"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. " - Filting diffraction

WebPosition the diffraction grating on the adhesive side of the sticker so it covers the hole you just made, then press it into place. Center the sticky side of the sticker with the diffraction grating over one end of the tube. Press and crimp the sides of the sticker around the end of the tube to secure it in place. This creates your eyehole.
