Product Description
F-theta lens, also known as focus lens and field lens, is an important component in laser marking machine, which focus the laser beam on the marking surface. It has several performance metrics as below:
1.Scan Field
The bigger field that the lens scans, the more popular the f-theta lens is. But too big scan field may cause many problems, such as big beam spot and deviation.
2.Focal length
Focal length (it has something to with f-theta lens working distance, but not equal to working distance).
a.Scan field is proportional to the focal length-bigger scan field will inevitably lead to longer working distance, which means more laser energy consumption.
b.The diameter of focused beam is proportional to the focal length, which means that when the scanning field increase to certain extent, the diameter is very big.The laser beam is not focused well, the laser energy density decreases badly ( the density is inversely proportional to the square of diameter) and cannot process well.
c. The longer the focal length is, the bigger the deviation is.

F-Theta focal points are ordinarily utilized in laser filtering frameworks that require a level picture plane and high goal. By presenting a particular measure of barrel contortion in the focal point, the picture tallness of the F-Theta focal point is relative to the examining edge. These diffraction restricted focal point frameworks can be designed to create the ideal spot measure and have a mutilation of under 0.25% of the whole field of view.
Sino-Galvo Tech. has practical experience in optical galvanometer scanner and its control framework's R&D, creation and deals. Our self-created laser cleaning framework has no harm to the substrate, can meet long-term activity of high force laser cleaning, and can be coordinated with different sorts of lasers.
