Features High Ability and Efficiency: The F Theta scan lens focus the collimated laser beam on the focus of a smaller area, increase the energy density of the laser beam, and improve the ability and efficiency of laser processing. Wide Application: The F Theta scan lens scanning range of the product is approx. 200 x 200mm/7.9 x 7.9in, and the maximum scanning angle is ±28°, suitable for semiconductor, optical fiber marking machine, high cost performance. High Speed and Accurate Laser Processing: The F Theta scan lens convert the change of the direction of the laser beam of the galvanometer into the change of the focus on the position of the processed material to achieve high-speed and accurate laser processing and processing. Accuracy Design: The design and processing accuracy is high, and all systems have reached the diffraction limit, low loss argon coating and precision optical elements. Special housing design optimizes performance. Features: The F Theta scan lens Fxθ has good linearity and low distortion, The inner circle of the breadth is good, and the uniformity is high, suitable for semiconductor, optical fiber marking machine, high cost performance.
