The resonant scanners developed and manufactured by FEMOTECH<\/strong> offer the highest level of precision<\/strong>, speed<\/strong>, and stability<\/strong>.<\/p>\n

With scan frequencies of up to 24 kHz<\/strong> and deflections of \u00b110 degrees (optical), they are among the most powerful of their kind on the scanner market. The precise tuning of mechanical and material properties ensures maximum efficiency, repeatability<\/strong>, and long-life cycle.<\/p>\n

A key component of these scanners is our flat<\/strong>, rigid mirror elements<\/strong> that remain undeformed even at high frequencies and deflections<\/strong>, thereby guaranteeing optimal beam quality. <\/strong>Their special coatings achieve reflectance of up to 99.99%<\/strong>, making them suitable for both broadband and wavelength-specific applications<\/strong>. The high reflectivity optimizes efficiency in optical systems<\/strong> and allows scanning at high power levels<\/strong>.<\/p>\n

Our resonant scanners feature a high-precision amplitude control<\/strong> that guarantees optimal reproducibility of scan results. Additionally, our systems can be operated at fixed frequencies (Fixed Frequency Mode [FFM]), which enables synchronization with asynchronously pulsed lasers<\/strong>.<\/p>\n

To achieve this, we developed an FPGA-based electronic control system that keeps the scanner in resonance, tunes its frequency, and measures its mirror position. The control electronics achieves an internal real-time resolution of 0.8 ns, which is used to generate all external trigger and synchronization signals. A programming API is provided for controlling the scanning system, which can be used in custom applications.<\/p>\n

<\/p>\n

Our scanners are used in laser marking<\/strong> for precise and fast inscriptions, as well as in surface processing<\/strong> for microstructuring and material removal. In addition, they are applied in micromachining<\/strong>, microscopy<\/strong> for high-resolution imaging, and LiDAR technology for three-dimensional environmental analysis.<\/p>\n

<\/p>\n

Manufacturing is carried out with the highest standards for dimensional accuracy and alignment<\/strong>. Careful final inspections<\/strong> ensure consistently high quality.<\/p>\n
