Wavelength Optoelectronics 1064nm Laser Field Mirror Marking Engraving Welding f-theta Flat Field YAG Scanning Lens

The F-Theta flat-field scanning lens is a standard component for laser marking, cutting, and engraving systems based on galvanometer scanning. The F-Theta flat-field scanning lens is optimized for the plane field in the plane through a multi-element air-spaced design, providing a flat field in the plane. Each component in the wavelength F-Theta flat-field scanning lens is coated with a high-power anti-reflection film, with an overall transmittance of > 95% and a damage threshold of > 5J/cm², 20ns, 20Hz, with quartz scanning lens series, optical glass material series, CO2 single-piece/multi-piece series, outer bracket with M85x1 standard interface.

Depending on the power and pulse width of the input laser, lenses of different materials are used. All-quartz scanning lenses are commonly used in high-power and picosecond laser applications.

Ronar-Smith ® F-Theta scanning lenses, commonly referred to as F-Theta lenses, are carefully designed and fabricated for a wide range of laser applications. With over a decade of expertise in optical grades and coating production, Ronar-Smith ® F-Theta lenses have some of the best optical properties in the world on the market.

F-ThetaLens - Optical Glass (SL)

F-Theta lenses are commonly used in vibrating mirror scanning systems for laser marking, engraving, and cutting; capable of transferring focus to many points within the scanning field. We also supply lens adapters to the world's leading suppliers of scanning heads.

F-ThetaLens - Fused Silica (SL-Q)

SL-QThe series F-Theta lenses have been developed for ultrafast lasers with short pulse widths and high pulse energy laser applications. These lenses are made of low-dispersion fused silica and are optically designed to avoid back reflections and ghost images.
