Product description

The AODF 4210-UV is G&H’s state-of-the-art acousto-optic deflector (AOD), designed for high-speed scanning applications requiring precision and reliability. Leveraging advanced RF carrier signal technology, it induces angular shifts in the diffracted first order proportional to the applied RF frequency. With the ability to handle UV wavelengths as low as 266 nm, this deflector provides agile, accurate, and reproducible beam positioning for both linear scanning and random addressability.

With solid-state construction and rugged packaging, the AODF 4210-UV delivers unmatched reliability and consistency, making it ideal for demanding applications such as micro machining, inspection systems, via drilling, and graphic imaging. Additionally, two-dimensional scanning is achievable by cascading two deflectors in series.

Highest Diffraction Efficiency

The AODF 4210-UV achieves diffraction efficiencies typically exceeding 85%, enabling optimal utilization of UV photons, reducing waste, and maximizing productivity in cost-intensive applications.

Flattest Diffraction Efficiency Versus Frequency Response

Paired with G&H’s 6000 series driver, the AODF 4210-UV ensures consistent processing results across the full scan angle, offering reliable performance for complex scanning needs.

Vertical Integration for Superior Quality

G&H controls every step of the AOD manufacturing process, including crystal growth, polishing, high-damage-threshold optical coatings, assembly, and testing. This vertical integration ensures the highest quality and reliability, cementing G&H’s reputation as a trusted industry leader.
