Infrared Laser F-Theta Lens

Infrared Laser F-Theta lenses, designed for infrared lasers (typically 1030-1080 nm), provide high-precision focusing with a consistent spot size across the scanning field. Ideal for laser marking, engraving, cutting, and micro-machining, these lenses feature high infrared transmission, low dispersion, and laser-damage-resistant coatings, ensuring stable performance under high-power, high-speed scanning for demanding industrial and high-resolution applications.

Key Features of Infrared Laser F-Theta Lens


The roundness of the focused light spot, with good consistency and high roundness between the center and edge light spots.


The focused spot is small, enabling precise micro-nano processing.


Extremely low energy loss, high transmittance,high damage threshold and small thermal lensing effect.
