The Laser processing tag focuses on optics that support cutting, marking, drilling, and micromachining with scanning or fixed-beam laser systems. Articles include case studies on achromatic beam expanders that handle multiple wavelengths with adhesive-free designs and robust AR coatings, improving beam quality and system flexibility. The tag also discusses F-theta lenses that provide distortion-corrected scanning over large fields, maintaining consistent spot size and linear positioning, which is essential for precise patterning and high throughput. Readers gain insights into how material selection, optical design, and coating choices impact durability and performance in high-power industrial environments. For engineers developing laser workstations, galvo-based scanners, or multiwavelength processing systems, this tag offers practical examples of how optimized optics can enhance process accuracy, speed, and reliability. It demonstrates Avantier’s experience in designing, prototyping, and manufacturing laser processing optics tailored to demanding production needs.
