Did You Know?

Galvo Scanner also known as “Galavanometer Scanner” or “Scanning Galvo” is an essential component in the laser beam steering architecture for many laser marking and laser engraving machines. The entire beam steering system that utilizes galvo scanners is typically comprised of two galvo scanners that provide angular steering of an incident laser beam around F and theta axes and a large aperture F-Theta lens that focuses the beam on to the sample being marked or engraved. That entire beam system is often called Galvo Scan Head and allows precise positioning of the focused laser beam within XY marking field on the focal plane. A typical Galvo Scanner is comprised of a high performance galvanometric motor that oscillates around its axis and an attached mirror that is rotated as the galvo scanner is activated. Galvanometer Scanners often utilize photoelectric sensors as a feedback mechanism that ensures the high reproducibility, motion linearity and accuracy of positioning. Most Galvo Scanners operate in a wide range of motion (often +/-40 degrees or higher) and offer a high degree of linearity of > 99%.

Frequently Asked Questions

Galvo Scanners also known as “Galvanometer Scanners” or “Scanning Galvos” or simply “Galvos” are an essential component in the laser beam steering technology for many laser markers and laser engravers. A galvo scanner is comprised of a high performance motor that is able to rotate (oscillate) around an axis at a fast angular speed and a permanently attached mirror, which it rotates. Their high degree of linearity and reproducibility allow steering laser beams with high speed and precision.

Brief Introduction to Galvo Scanners

Galvanometer scanners, commonly known as galvo scanners, are pivotal components in laser systems, enabling precise and rapid control of laser beam positioning. By utilizing small mirrors mounted on galvanometers, these scanners direct laser beams with high accuracy, making them indispensable in various applications such as laser marking, engraving, cutting, and welding.

The core functionality of a galvo scanner lies in its ability to swiftly adjust the angle of mirrors in response to electrical signals, thereby steering the laser beam across the target surface. This mechanism allows for high-speed operations, with some systems achieving scanning speeds exceeding 10 meters per second . Such rapid movement is crucial in applications requiring swift and precise laser beam positioning.

In laser marking and engraving, galvo scanners facilitate the creation of intricate designs and patterns on various materials, including metals, plastics, and ceramics . Their high precision ensures consistent quality, making them ideal for applications in the automotive, aerospace, and electronics industries.

Beyond industrial applications, galvo scanners are employed in medical fields, particularly in ophthalmology and dermatology, where precise laser control is essential for procedures like retinal treatments and skin resurfacing . Their ability to deliver controlled laser exposure minimizes damage to surrounding tissues, enhancing patient safety and treatment efficacy.

The versatility of galvo scanners extends to scientific research, where they are integral in confocal microscopy and laser scanning microscopy. These applications benefit from the scanners' ability to rapidly and accurately direct laser beams, enabling high-resolution imaging of biological specimens.

Advancements in galvo scanner technology have led to the development of systems with improved thermal stability and reduced drift, ensuring consistent performance over extended periods. Additionally, integration with advanced control software allows for real-time adjustments and complex pattern generation, further expanding their capabilities.

In summary, galvo scanners are essential components in modern laser systems, offering unparalleled speed and precision in directing laser beams. Their applications span a wide range of industries, from manufacturing and medicine to scientific research, underscoring their significance in advancing technology and improving operational efficiency.
