Precise Acousto-Optic Multi-Channel Modulators
Featured Product from CASTECH, Inc.

CASTECH's Acousto-Optic Multi-Channel Modulators (AOMM) are advanced modulation devices designed for independent control of multiple laser beams or line-collimated light. Utilizing integrated transducer arrays and high-performance acousto-optic crystals, these devices enable the precise modulation and deflection of multiple beams.
Compared to traditional single-channel AOMs, AOMMs offer:
- Increased Beam Modulation: Capable of modulating up to 10 channels simultaneously.
- Enhanced Efficiency: Reduced scanning rates and bandwidth requirements for optimized performance.
- Improved Linear Characteristics: Superior performance in laser systems requiring consistent modulation.
CASTECH's AOMMs are manufactured using premium materials such as low-scatter fused quartz, crystalline quartz, and tellurium dioxide, ensuring:
- Low Insertion Loss
- High Laser Damage Threshold
- Minimized Crosstalk through advanced optical and electronic design.
These features make AOMMs ideal for diverse applications, including:
- Laser Marking
- Micromachining
- High-Resolution Printing
- Material Processing
- 2D Information Processing
- Optical Digital Computing
