Precision Telecentric F-Theta Scan Lens for 355nm UV Laser Marking – Fused Silica Scan Lens for High Resolution Engraving

Telecentric F-Theta Scan Lens By Fused Silica

The Telecentric F-Theta Scan Lens is a precision optical solution that directs off-axis beams to focus normal to the workpiece, achieving the same perpendicularity as on-axis beams. This unique telecentric design minimizes field curvature and distortion, while ensuring consistently high spot quality throughout the scan field. Ideal for high-power and ultrafast lasers, our TSL-Q Series lenses are built to reduce thermal lensing and eliminate focal shift—providing reliable, high-throughput performance for demanding industrial and scientific applications.
