Volume holograms are used as tunable optical filters to produce monochromatic images, also known as hyperspectral imaging.

The use of tunable filters is a completely new feature in 8 to 10 m class telescopes that will allow observing the very faint and distant emission line objects.

Acousto-optical tunable filter, a piezoelectric optical device AotF may refer to:

It "provides a new generation of instrumental observation techniques such as the tunable filters, the charge-shuffling capability in the CCD detectors, etc."

Terahertz metamaterial devices have been demonstrated in the laboratory as tunable far-infrared filters, optical switching modulators, and absorbers.

The acousto-optic tunable filter, especially the dazzler, which can generate variable pulse shapes, is based on this principle.

Instruments intended for chemical imaging in the NIR may use a 2D array detector with an acousto-optic tunable filter.

Wavelength selection can be accomplished with a fixed filter, tunable filter, spectrograph, an interferometer, or other devices.

Equipped with a stepper motor and electronics, a tunable optical filter that tunes center transmission wavelength over C-band or L-band by remote control can be achieved.

Its products included the Apollo line of lasers, as well as optical switches, polarization controllers, tunable filters, spectral monitors, and universal transponders.
