Collinear acoustooptic filtration in a long crystal is considered, where the acoustic power density varies on account of damping and divergence. An estimate is made of the limiting passband for such a filter in the visiblerange. It is shown for a quartz crystal that a length of about 20 cm may be taken as optimal, while the realistically attainable passband is 0.1 nm.
