The graph starts with a single bell curve representing an idealized bandpass filter. Swiping up, down, left or right allows you to alter the bandwidth and maximum transmittance of the filter. The buttons below provide more information about key characteristics of the filter. Swiping the small spectrum changes the central wavelength of the filter.
