ST Series electro-optic deflectors are the most efficient mechanisms for changing the angle of a laser beam. EOD can scan a laser beam over arange of angles or control the output angle of a laser beam.
ST Series electro-optic deflectors are the most efficient mechanisms for changing the angle of a laser beam. EOD can scan a laser beam over arange of angles, or control the output angle of a laser beam with great accuracy. We employ a quadrapole electric field in an electro-optic material to produce a linear refractive index gradient proportional to the applied signal voltage.
