Comprehending Galvo Scanner Specifications
When evaluating a galvo scanner, it is important to be familiar with the key specifications that determine its performance and suitability for your application. These specifications serve as a benchmark for comparing different models and ensuring compatibility with your existing setup.
Scanning angle is a fundamental parameter that determines the field of view of a scanner. A larger scan angle can cover a larger area, which is very useful for applications that require a lot of marking or processing. However, it is important to note that increasing the scan angle may come at the expense of reduced accuracy or speed.
Another key specification is the aperture size, which determines the maximum beam diameter that can pass through the scanner. This factor is particularly important when using high-power lasers or applications that require a large spot size. Ensuring that the galvo scanner ’s aperture size matches the laser beam characteristics is critical to achieving optimal performance.
Positioning speed and acceleration are key indicators that affect the overall throughput of the laser system, especially in applications with frequent positioning and complex path motion. Higher speed and acceleration can reduce processing time, but may also affect accuracy. It is critical to strike a balance between speed and accuracy based on specific application requirements.
Resolution is another key factor, especially for applications that require high precision. The resolution of a galvo scanner is usually measured in microradians, which determines the smallest increment of movement the mirror can achieve. Higher resolution means finer control over the positioning of the beam, which is critical for complex marking or cutting tasks.
When considering a laser marking galvo scanner, pay close attention to its wavelength compatibility.
