Continuously Varying Thickness Interference Bandpass Filter for the Visible Spectral Range: Using Ion Beam Sputter Deposition

<div>A zoom in at the measured transmission of the bandpass filter. (a) The average transmission inside the passband is 88%. (b) Maximum transmission outside the passband is a mere 1.6% [<a href="/journals/amse/2022/8390315/#B22">22</a>].</div>
