Overview
Product Details
The F-Theta flatfield scanning lens, also known as the field mirror and F-theta Focusing lens,is a professional industrial laser device based on galvanoscopic scanning oflaser marking, cutting and engraving systems. There are a wide variety including F-Theta lenses and telecentric lenses, the recommended ones on this page are F-Theta lenses for laser wavelengh of 1064nm, 355nm and 10.6μm.
About how to choose scan scope:
A large scanningrange means that there is no need to move the processed material, and the lasercan scan a large range at once. However, the focus spot also increases, thedistortion increases, the focal length increases, and the working axis alsoneeds to be raised.
The extension ofworking distance inevitably leads to the loss of laser energy. Compared withsmall format field mirrors on the same equipment, laser energy will beweakened.
In addition, insufficient thinness of the spot can lead to a very rapid decrease in thepower density of the laser (power grams are inversely proportional to thesecond power of the spot diameter),reducing the processing efficiency.
To ensure both scanning range and processing efficiency, it is necessary to increase the power of the laser. Therefore, the power of the laser, the working focus of the laser system and the actual processing needs simultaneously constrain the selection of the field mirror scanning range. You can provide us with specific feedback on the actual situation to obtain more accurate recommendations.
