The 1064nm laser F-THETA field lens provided by Suntop adopts high-quality optical design and modern manufacturing technology. Widely used in laser engraving, laser marking industry. F-THETA field lens can obtain high-quality flat-field effect and minimum geometric distortion under the premise of ensuring that the spot reaches the diffraction limit. Suntop laser provides a variety of product models and customer customization options.
• Focusing the collimated laser beam on a smaller area of the focal point increases the energy density of the laser beam and improves the capability and efficiency of laser processing.
• Converts the change of laser beam direction by the oscillator into the change of focal point on the position of the processed material, thus realizing high-speed and precise laser processing machining.

Common applications of f theta lens
• Perforating and precision cutting of metal or pottery (e.g. micro holes in PCBs)
• Plastic welding (e.g. fusing plastics without filler material)
Shaping and piercing of metal or non-metallic materials (e.g. openings/vents)
