F-Theta scan lens is a high-precision scanning and focusing optical component specifically designed for 800nm near-infrared lasers, widely used in ultrafast laser processing applications. Manufactured from low-dispersion fused silica with optimized optical design, it is suitable for high pulse energy, ultra-short pulse width laser precision scanning applications.

Key Advantages

This lens series is optically optimized for the 800nm wavelength band, ensuring uniform focus spots and extremely low distortion across the entire scan field. Utilizing high-quality fused silica material, it offers excellent thermal stability and high laser damage threshold, making it particularly suitable for high-power laser applications including welding, cleaning, and surface structuring. The optical design effectively suppresses thermal lensing effects and focal shift, maintaining beam quality consistency during long-duration continuous processing.

Specifications

The 800nm F-Theta scan lens series offers various models with scan fields covering 70×70mm to 180×180mm. Typical products include FL-800-70-110 (110mm focal length, 70×70mm scan field), FL-800-112-167 (167mm focal length, 112×112mm scan field), and FL-800-180-275 (275mm focal length, 180×180mm scan field). The standard interface is M85×1 thread, compatible with mainstream galvo scanning systems.

Typical Applications

The 800nm F-Theta lens is widely used in high-precision laser marking, material micromachining, laser cleaning, laser welding, and optical scanning imaging in scientific research applications.
