Key Optical & Performance Features
Flat-Field Focal Precision
Maintains consistent focal spot size and energy distribution from the center to the extreme edges of the marking field.
High Transmittance AR Coating
Advanced anti-reflection coatings reduce optical power loss, preventing internal reflections and thermal lens distortion.
Universal Galvo Compatibility
Standardized threaded mounting allows easy retrofitting onto most fiber laser marking heads and scanning galvos.

Frequently Asked Questions
How do I select the right focal length (F-number) for my marking area?
Shorter focal lengths (e.g., F=160mm) yield a smaller laser focal spot size with higher power density, ideal for fine engraving. Longer focal lengths (e.g., F=254mm or F=330mm) provide a larger marking field for big workpieces.
How should I safely clean the optical surface of the F-Theta lens?
Use an air blower to remove dust first. Then, gently wipe the optic in one direction using lens cleaning tissue moistened with high-purity anhydrous alcohol. Never scrub back and forth to avoid scratching the AR coating.
Is this lens compatible with CO2 or UV laser marking machines?
No, this specific lens is optimized for the 1064nm infrared wavelength used by fiber lasers. For CO2 (10.6μm) or UV (355nm) lasers, dedicated wavelength-matched lenses must be used.
