Acousto-Optic Polychromatic Modulators
Low Side Lobes Versions
The AOTFnC is a special acousto-optic tunable filter
which uses the anisotropic interaction inside a tellurium
dioxide crystal to control independently or simultaneously
different lines from an incoming UV or
VISIBLE laser light (White laser, Ar+, Kr+, HeNe, DPSS, Dye…).
Up to 8 distinct lines can be mixed and separately modulated
in order to generate different colorimetric
patterns.
The specific crystal cut of the AOTF.nC produces good
diffraction efficiency (> 90%), narrow resolution (1-2
nm), a low cross-talk between lines, and high extinction ratio.
The large separation angle between 0 and 1st orders,
as well as the excellent output chromatic colinearity
(<0.2 to <0.3 mrd ) make this AOTF a powerful tool for
free space or fiber pigtailed applications.
Its associated thermal stabilisation maintains stable
diffraction efficiency and reduces dramatically beam
drift with single mode fiber pigtailing. This is a major
advantage for high sensitivity applications.
