F-theta Lens
What Is FTheta Lens
F-theta Lens
Han's Scanner f theta scan lensseries products are the most commonly used parts in the laser field. After our continuous improving and updating, we have improved quality of telecentric F-theta lens, following the development direction of international industrial laser cutting, and has developed a series of products. In addition to regular marking F-theta lens, there are water-cooled F-Theta lenses for higher power, as well as for faster pulses of ultra-fast lasers. Common Fθ scan laser lenscan be widely used in various laser application fields such as laser marking, engraving and scribing.
Key Features Of F-theta Lens
Wavelength Compatibility: Designed to accommodate various laser wavelengths, such as 1064nm, 532nm, and 355nm, ensuring versatility for different applications.
Focal Length Options: The F-θ lens series provides a range of focal lengths, allowing users to select the appropriate lens based on the specific requirements of their laser systems.
Entrance Pupil Diameter Variation: Offers options with different entrance pupil diameters to suit the diverse needs of laser applications, providing flexibility in system design.
Power Adjustment: Subdivided into products with different power specifications, enabling users to choose the optimal F-theta lens based on the power requirements of their laser systems.
Telecentric Design: Incorporates a telecentric design, ensuring that the chief rays are parallel to the optical axis. This feature of telecentric F-theta lens is valuable for maintaining consistent image quality throughout the field of view.
Precision for Ultrafast Lasers: Developed in response to the latest trends in laser technology, the F-theta scan lens series includes a specialized flysecond optical system, catering to ultrafast laser applications.
What Is F-theta Lens?
An f-theta lens, including telecentric f theta lens, is a type of lens used in laser marking, engraving, and scanning systems. The term 'f-theta' refers to the relationship between the focal length (f) and the angle (theta) of the laser beam as it scans across a flat plane. Unlike regular lenses that create a linear increase in distance with the angle, f-theta lenses produce a linear increase in distance for each unit of angle over a flat field.
The primary function of an f-theta scan lens is to ensure a consistent spot size and marking quality across the entire marking field. This is crucial in applications where precision and uniformity of laser marking or engraving are essential.
F-theta scan lenses are commonly used in laser systems for tasks such as marking barcodes, serial numbers, patterns, or intricate designs on materials like metals, plastics, and ceramics. The flat field of focus provided by these lenses allows for accurate and distortion-free laser marking over a specified area."
