Devices designed specifically for high-speed solid-state scanning of light beams

Acousto-optic deflectors (AODF) can achieve laser beam scanning by changing the RF driving frequency, and the scanning position can achieve random position, continuous line scanning, and sequential point deflection. Depending on crystal, wavelength, and beam size, scan rates in excess of 200 MHz can be achieved, along with precise position control of nRad.
The optimal efficiency of an AOD typically requires the input laser beam to be set at a Bragg angle, when scanning the laser beam a Bragg angle mismatch occurs, this is due to the fact that the AOD can only be optically aligned at one drive frequency. This generally results in lower efficiency. CASTECH's team has the design experience to cleverly solve the problem, such as using longitudinal modes and using phased array piezoelectric cells within the transducer to design and produce large bandwidth AODs with high resolution.
CASTECH design AOD for 1D and 2D scanning, and together with the specially developed broadband RF driver, we can realize various control methods such as frequency sweeping and chirping, which makes it easy for customers to realize multiple functions quickly.

 

Applications:

Laser direct writing             

Wafer inspection            

Precision circuit board drilling  

Biological cell detection      

Optical tweezers

CASTECH's products are produced independently throughout the entire process and can be customized according to customer needs. Refer to the following list for standard products.
