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.

The larger water droplets produced by Rain Curtain technology prevent misting and airborne evaporation so the right amount of water is delivered to the right place, saving you water and money.

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.

Scanner Optics F-Theta lens series 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 lens can be widely used in various laser application fields such as laser marking, engraving and scribing.

Relax with the knowledge your landscape is being watered by reliable 5000 Series Rotors and industry-leading Rain Curtain Nozzle Technology. Rain Bird® 5000 Series Rotors are ideal for medium to large-size lawns and evenly distribute water from 25 to 50 feet.

F-theta lens are optical components used in laser scanning systems, primarily for applications requiring a flat field of view such as laser scanning, marking, engraving, and cutting systems. By introducing a specific amount of barrel distortion, these scan lens can produce a flat field on the image plane, making them an ideal choice. F-theta lens can create a flat field suitable for various applications, including laser welding, laser marking/engraving, laser drilling, laser displays, LIDAR, scanning laser microscopy, and optical coherence tomography.
