Acousto-optic tunable filters improve optical microscopy

The acousto-optic tunable filter is playing an increasingly important role in modern optical microscopy. In the latest-generation laser-scanning confocal microscopes, these devices modulate both the wavelength and amplitude of the laser light used as the illumination beam.
