F-theta Scan Lens are commonly used with galvanometer scanning mirrors in laser engraving, cutting and marking systems. The reason why it is named as F-theta lens is that the radial image height equals to focal length multiplied by the angle of the chief ray made in the object space. Typically the F-theta distortion of this lens is kept at less than 1% so that it produces a precise spot on the flat field on image plane.
Our 1064nm F-Theta Lenses feature multiple elements for the ultimate in image resolution. An air-spaced design and high efficiency AR coatings guarantee excellent throughput and durability. An industry-standard M85 threading on all F-theta lenses allows for easy mounting and simple retrofitting of OEM systems.
We have many types of 1064nm F-theta lenses, such as F100-W1064, F160-W1064, F210-W1064 and so on. You can make a chice according to your need. We can also customize the lenses for you.
532nm F-theta lens is Zhuorui's new product. Our designer make the drawings with the professional softs Code V and Zemax.
532nm F-theta lens is used on green laser marking machine. By now, we have designed and manufactured F254-W532 and F435-W532. The square field sizes are 175mm*175mm and 300mm*300mm respectively.
We will continue to design 532nm F-theta lenses with different focal lengths. They will help your green laser marking machine work well for sure.
