PL Optics‘ AOTF Acousto-Optic Tunable Filter provides fast, precise, multi-channel wavelength selection across 400-2000 nm for supercontinuum light sources, ideal for advanced imaging and spectroscopy.
The AOTF Acousto-Optic Tunable Filter is a plug-and-play dispersion device for supercontinuum light sources, capable of delivering 8 independent monochromatic channels within a single laser beam. Three different AOTF crystals cover the 400–2000 nm wavelength range. The standard output is free-space collimated, and an optional fiber coupler can be installed for fiber output.
