CO₂ Laser Singlet F-Theta Scan Lens

F-Theta lenses are commonly used in conjunction with galvanometer scanning mirrors in laser engraving, cutting, and marking systems. Typically the F-Theta distortion of the lens is kept less than 1% so that it is able to produce a precise spot in the flat field on the image plane.

Product Description

CO₂ Laser Singlet F-Theta Scan Lens

Eternal Optics manufactures precision CO₂ Laser Singlet F-Theta Scan Lenses designed for reliable and efficient 10.6 μm CO₂ laser marking, engraving, cutting, and industrial processing applications. Featuring a single-element optical design, our F-Theta lenses provide excellent scanning performance, high transmission efficiency, and cost-effective solutions for a wide range of CO₂ laser systems.

Our 10.6µm Singlet F-Theta Scan Lenses are optimized for CO₂ laser wavelengths and manufactured using high-quality infrared optical materials such as ZnSe (Zinc Selenide). With advanced anti-reflective coatings, these lenses deliver high transmission, low absorption, and stable optical performance under continuous laser operation.

Designed for use with galvanometer scanning systems, CO₂ F-Theta Lenses convert scanner angular motion into a precise linear marking field, ensuring accurate positioning and consistent laser processing results across the working area.
