Wavelength 1940nm Scan Lens STK-160A-14-1940
Our f-theta flat-field lenses achieve diffraction-limited image quality across the full field of view, with actual distortion controlled within 0.20%. The quartz-series field lenses have a higher laser damage threshold, withstand high-power lasers, and provide better thermal stability to reduce thermal focal shift. The main technical specifications of the standard F-theta scanning lenses meet or closely approach those of the most advanced comparable overseas products. They are widely used for laser marking, cutting, and drilling, enabling rapid, uniform scanning over the entire processing surface. Their advantages include a comprehensive range, reliable quality, timely delivery, attentive service, and better cost performance, meeting diverse processing requirements.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
