Fiber Laser Marking Focusing Lens
A Fiber Laser Marking Focusing Lens, often called an F-Theta Scan Lens, is an optical lens used in fiber laser marking systems to focus the laser beam onto a flat plane with precision and uniformity. It ensures distortion-free marking across the defined working field.
Description
Fiber Laser Marking Focusing Lens Description
The Fiber Laser Marking Focusing Lens, also known as the F-Theta Scan Lens, is an optical lens specifically designed to focus the laser beam onto a flat marking surface with consistent precision.
Designed for fiber lasers operating in the infrared spectrum, typically at 1064nm wavelength.
It is an essential component in fiber laser marking systems, providing distortion-free and high-speed marking, engraving, or cutting.
This lens is ideal for applications requiring accurate and uniform results over a defined working area.
