Electro-Optic Deflectors

Deflect laser beams the quick and accurate way

Electro-optic deflectors are the fastest and most effective tools for changing the direction of laser beams. The deflectors continuously deflect a laser beam using predefined angle ranges (scanning) or implement fast switching between freely selectable deflection angles (random access) with extreme precision.

During this process, a special non-linear electro-optic effect in certain, well-defined cut crystals of selected transparent materials is used to produce a linear refractive index gradient that is proportional to the signal voltage present. When a laser beam passes the gradient in a perpendicular manner, it is deflected slightly, whereby the deflection angle can be controlled due to the externally applied voltage.
