One-Dimensional Acousto-Optic Deflectors
Product description：
Acousto-optic deflectors (AODF) can provide precise spatial control of an optical beam by frequency tuning of RF driver.The response time within a hundred nanoseconds. It is designed based on the deflection of light when it travels through an diffraction grating created by acoustic wave optical propagating within the medium.
CASTECH's AODF adopts TeO2 crystal as the acousto-optic medium. Benefited from our well known expertise in crystal growing and process technology. CASTECH promise the high performance of deflectors characterized with low insertion loss, high laser damage threshold, high consistency of power and diffraction efficiency across the full scan angle.
Applications：
●Laser display
●Micromachining
●Heterodyne interferometer
●Laser tweezers
●Optical inspection
